Kubuntu General News: Kubuntu 20.10 Groovy Gorilla released

1 day 12 hours ago

KDE Plasma-Desktop

The Kubuntu community are delighted to announce the release of Kubuntu 20.10 Groovy Gorilla. For this release Kubuntu ships with Plasma 5.19.5 and Applications 20.08. The desktop carries the fresh new look and gorgeous wallpaper design selected by the KDE Visual Design Group.


Cloud Ready

With the rapid growth in cloud native technologies the kubuntu community recognise that Kubuntu users need access to cloud and container technologies.
Kubuntu 20.10 also includes LXD 4.6 and MicroK8s 1.19 for resilient micro clouds, small clusters of servers providing VMs and Kubernetes.

Kubuntu 20.10 includes KDE Applications 20.08.

Dolphin, KDE’s file explorer, for example, adds previews for more types of files and improvements to the way long names are summarized, allowing you to better see what each file is or does. Dolphin also improves the way you can reach files and directories on remote machines, making working from home a much smoother experience. It also remembers the location you were viewing the last time you closed it, making it easier to pick up from where you left off.

For those of you into photography, KDE’s professional photo management application, digiKam has just released its version 7.0.0. The highlight here is the smart face recognition feature that uses deep-learning to match faces to names and even recognizes pets.

If it is the night sky you like photographing, you must try the new version of KStars. Apart from letting you explore the Universe and identify stars from your desktop and mobile phone, new features include more ways to calibrate your telescope and get the perfect shot of heavenly bodies.

And there’s much more: KDE’s terminal emulator Konsole and Yakuake; Elisa, the music player that looks great ; the text editor Kate; KDE’s image viewer Gwenview; and literally dozens of other applications are all updated with new features, bugfixes and improved interfaces to help you become more productive and making the time you spend with KDE software more pleasurable and fun.

Ubuntu Studio: Ubuntu Studio 20.10 Released

1 day 15 hours ago

The Ubuntu Studio team is pleased to announce the release of Ubuntu Studio 20.10, code-named “Groovy Gorilla”. This marks Ubuntu Studio’s 28th release. This release is a regular release, and as such it is supported for nine months until July 2021.

Since it’s just out, you may experience some issues, so you might want to wait a bit before upgrading. Please see the release notes for a complete list of changes and known issues.

You can download Ubuntu Studio 20.10 from our download page.

If you find Ubuntu Studio useful, please consider making a contribution.


Due to the change in desktop environment this release, direct upgrades to Ubuntu Studio 20.10 are not supported. We recommend a clean install for this release:

  1. Backup your home directory (/home/{username})
  2. Install Ubuntu Studio 20.10
  3. Copy the contents of your backed-up home directory to your new home directory.
New This Release

The biggest new feature is the switch of desktop environment to KDE Plasma. We believe this will provide a more cohesive and integrated experience for many of the applications that we include by default. We have previously outlined our reasoning for this switch as part of our 20.04 LTS release announcement.

This release includes Plasma 5.19.5. If you would like a newer version, the Kubuntu Backports PPA may include a newer version of Plasma when ready.

We are excited to be a part of the KDE community with this change, and have embraced the warm welcome we have received.

You will notice that our theming and layout of Plasma looks very much like our Xfce theming. (Spoiler: it’s the same theme and layout!) Audio Studio Controls replaces Ubuntu Studio Controls

Ubuntu Studio Controls has been spun-off into an independent project called Studio Controls. It contains much of the same functionality but also is available in many more projects than Ubuntu Studio. Studio Controls remains the easiest and most straightforward way to configure the Jack Audio Connection Kit and provide easy access to tools to help you with using it.

Ardour 6.3

We are including the latest version of Ardour, version 6.3. This version has plenty of new features outlined at the Ardour website, but contains one caviat:

Projects imported from Ardour 5.x are permanently changed to the new format. As such, plugins, if they are not installed, will not be detected and will result in a “stub” plugin. Additionally, Ardour 6 includes a new Digital Signal Processor, meaning projects may not sound the same. If you do not need the new functionality of Ardour 6, do not upgrade to Ubuntu Studio 20.10.

Other Notable Updates

We’ve added several new audio plugins this cycle, most notably:

  • Add64
  • Geonkick
  • Dragonfly Reverb
  • Bsequencer
  • Bslizr
  • Bchoppr

Carla has been upgraded to version 2.2. Full release announcement at kx.studio.

Video OBS Studio

Our inclusion of OBS Studio has been praised by many. Our goal is to become the #1 choice for live streaming and recording, and we hope that including OBS Studio out of the box helps usher this in. With the game availability on Steam, which runs native on Ubuntu Studio and is easily installed, and with Steam’s development of Proton for Windows games, we believe game streamers and other streamers on Youtube, Facebook, and Twitch would benefit from such an all-inclusive operating system that would save them both money and time.

Included this cycle is OBS Studio 26.0.2, which includes several new features and additions, too numerous to list here.

For those that would like to use the advanced audio processing power of JACK with OBS Studio, OBS Studio is JACK-aware!


We have chosen Kdenlive to be our default video editor for several reasons. The largest of which is that it is the most professional video editor included in the Ubuntu repositories, but also it integrates very well with the Plasma desktop.

This release brings version 20.08.1, which includes several new features that have been outlined at their website.

Graphics and Photography Krita

Artists will be glad to see Krita upgraded to version 4.3. While this may not be the latest release, it does include a number of new features over that included with Ubuntu Studio 20.04.

For a full list of new features, check out the Krita website.

Darktable This version of the icon seemed appropriate for an October release. :)

For photographers, you’ll be glad to see Darktable 3.2.1 included by default. Additionally, Darktable has been chosen as our default RAW Image Processing Platform.

With Darktable 3.2 comes some major changes, such as an overhaul to the Lighttable, A new snapshot comparison line, improved tooltips, and more! For a complete list, check out the Darktable website.

Introducing Digikam

For the first time in Ubuntu Studio, we are including the KDE application Digikam by default. Digikam is the most-advanced photo editing and cataloging tool in Open Source and includes a number of major features that integrate well into the Plasma desktop.

The version we have by default is version 6.4.0. For more information about Digikam 6.4.0, read the release announcement.

We realize that the version we include, 6.4.0, is not the most recent version, which is why we include Digikam 7.1.0 in the Ubuntu Studio Backports PPA.

For more information about Digikam 7.1.0, read the release announcement.

More Updates

There are many more updates not covered here but are mentioned in the Release Notes. We highly recommend reading those release notes so you know what has been updated and know any known issues that you may encounter.

Introducing the Ubuntu Studio Marketplace

Have you ever wanted to buy some gear to show off your love for Ubuntu Studio? Now you can! We just launched the Ubuntu Studio Marketplace. From now until October 27th, you can get our special launch discount of 15% off.

We have items like backpacks, coffee mugs, buttons, and more! Items for men, women, and children, even babies! Get your gear today!

Ubuntu Blog: Build a Raspberry Pi Desktop with an Ubuntu heart

1 day 15 hours ago

On the 22nd October 2020, Canonical released an Ubuntu Desktop image optimised for the Raspberry Pi. The Raspberry Pi Foundation’s 4GB and 8GB boards work out of the box with everything users expect from an Ubuntu Desktop. It is our honour to contribute an optimised Ubuntu Desktop image to the Raspberry Pi Foundation’s mission to put the power of computing into people’s hands all over the world.

<noscript> <img alt="" src="https://res.cloudinary.com/canonical/image/fetch/f_auto,q_auto,fl_sanitize,c_fill,w_720/https://ubuntu.com/wp-content/uploads/2bc4/GG_blog-post-RPi_3.png" width="720" /> </noscript> The right hardware

Since the Raspberry Pi Foundation began its mission, users have been using their boards to run everything in their lives. Whether that’s making DIY devices, learning to code or building products, it was made possible by Raspberry Pis. But running a full-featured, LTS desktop that can handle the expectations of everyday users, without technical knowledge, wasn’t really possible. Until recently.   

The Raspberry Pi 4 debuted with the graphics, RAM and connectivity needed for a Linux workstation. Users finally had the hardware to make a Raspberry Pi into a viable primary PC. But there were still issues. Most importantly, a lot of the desktop options either required a non-zero amount of technical knowledge or weren’t suited for long term use. Usually because of a lack of upstream support or running unmaintained, niche software.

Canonical, the company that publishes Ubuntu, is and continues to be a long term fan of the Raspberry Pi Foundation. Together, our missions to make technology more accessible to people all of the world aligns, and both organisations understand the value of an active and trusting community. So, when the Raspberry Pi 4 launched with the capabilities to run a full-fat Ubuntu Desktop, we didn’t blink.

<noscript> <img alt="" height="446" src="https://res.cloudinary.com/canonical/image/fetch/f_auto,q_auto,fl_sanitize,c_fill,w_446,h_446/https://ubuntu.com/wp-content/uploads/a473/Ubuntu-and-Raspberry-Pi-01.png" width="446" /> </noscript> An engineering collaboration

The Ubuntu Desktop team, the Foundations team, and the Kernel team got to work. While they were cooking, we reached out to the Raspberry Pi Foundation to strengthen our relationship and express our appreciation for their work. One thing led to another, and seeing the value in collaboration; we began to work together on some common projects. One of which is this full Ubuntu Desktop for Raspberry Pi

After months of work and plenty of collaboration, the Ubuntu Desktop image for the Raspberry Pi is here! On a Raspberry Pi 4 (with 4GB or 8GBs RAM) you can do everything the average desktop user would expect. Surf the web, watch the latest films, develop new software, read the news, or do your shopping. All from the comfort of a Raspberry Pi. 

<noscript> <img alt="" src="https://res.cloudinary.com/canonical/image/fetch/f_auto,q_auto,fl_sanitize,c_fill,w_720/https://ubuntu.com/wp-content/uploads/16c3/05_plex.png" width="720" /> </noscript>

This joining of Raspberry Pi, the incredible maker and educational hardware, used in schools, factories and robots alike, and the Ubuntu Desktop, best known for its leading cloud and desktop offerings, delivers not only a low-cost, versatile desktop experience but also a gateway to all of open source software. The Ubuntu Desktop on Raspberry Pi comes with committed long term support and a deepening collaboration upstream which, we hope, will only continue to flourish.   

The open source ARM workstation

Ubuntu on Raspberry Pi is not only a great place to start with Ubuntu, and Linux in general, but is already used and favoured by inventors and entrepreneurs, too. Start learning to code, develop applications or take it production, all from one board, with one operating system (OS).

Not only that, the Raspberry Pi is an ARM computer, like Android or iOS phones. You can build and test apps for ARM on a low-cost board that is still powerful enough to orchestrate workloads, manage virtual machines or run a micro-cloud.

What all this means is that a Raspberry Pi with Ubuntu is a path into the world of ARM computing, ARM development and ARM-based products. Both at the edge, on workstations and in the cloud. Most IoT devices out there already run ARM. The Raspberry Pi is a tried and tested ARM board that is the brains of countless devices. In people’s homes as a hobby, and in production as enterprise-grade products. Ubuntu is there too with its embedded version, Ubuntu Core. Ubuntu optimised to work on the Raspberry Pi to give users an industry-standard, secure, minimal OS from production. 

<noscript> <img alt="" src="https://res.cloudinary.com/canonical/image/fetch/f_auto,q_auto,fl_sanitize,c_fill,w_720/https://ubuntu.com/wp-content/uploads/4cdb/armlogo.png" width="720" /> </noscript>

But this has been the case for some time. What’s new is that Ubuntu Desktop on Raspberry Pi delivers a more accessible and more familiar experience to get going with ARM. With Apple announcing their ARM-based Mac intentions, and the likes of Amazon’s Graviton2 making high-performance ARM compute cost-effective, we will soon see companies and app developers across industries move to ARM. Or risk losing out.

Get it

To get the Ubuntu Desktop from the Raspberry Pi Foundation, download their Raspberry Pi Imager application. The app is available on macOS, Windows and Linux, and the new Ubuntu Desktop image is baked up inside. To get the image straight from Canonical, head to the website and look atop the Ubuntu Server and Core images.

<noscript> <img alt="" src="https://res.cloudinary.com/canonical/image/fetch/f_auto,q_auto,fl_sanitize,c_fill,w_720/https://ubuntu.com/wp-content/uploads/590f/Screenshot-from-2020-10-22-14-14-39.png" width="720" /> </noscript>

To find out more about the benefits of the image go to the website and have a read. Or, watch this video where Martin Wimpress, Director of Engineering for Ubuntu Desktop and I, Product Manager of IoT and Makerspace initiatives talk through the whole process.

Then, once you have the image, know all the context, and know-how to get going, there’s always more. On the Desktop itself, start using it and Tweet @ubuntu whatever it is you’re using it for. Or, fill out this form for a chance to win some free stuff. We’d love it just to see that you’ve got it up and running. Then, head over to our community forum to leave any comments or feedback you have too. 

Or, if you’re interested in getting more out of Raspberry Pis, there are plenty of more options too. For cloud enthusiasts, you can try MicroK8s Raspberry Pi clustering, to orchestrate and manage workloads and practice your Kubernetes. Or for embedded/IoT device developers, take a look at Ubuntu Core. Build a portfolio of appliances, that turns your Raspberry Pi into a dedicated device to do one thing, perfectly.

The full Ubuntu Desktop is now available for the Raspberry Pi. With it, users have access to a full Linux workstation on the world’s most versatile and popular single-board computer. This development paves the way not only to a more practical Raspberry Pi desktop experience but also to the new world of cloud computing and applications running on ARM. We have a deep admiration for the Raspberry Pi Foundation and look forward to working with them and their technology more in the future.

Ubuntu Blog: Ubuntu 20.10 on Raspberry Pi delivers the full Linux desktop and micro clouds

1 day 23 hours ago
<noscript> <img alt="" src="https://res.cloudinary.com/canonical/image/fetch/f_auto,q_auto,fl_sanitize,c_fill,w_720/https://ubuntu.com/wp-content/uploads/2ad9/Groovy-Gorilla_WP_4096x2304.jpg" width="720" /> </noscript>

22nd October 2020: Canonical today released Ubuntu 20.10 with optimised Raspberry Pi images for desktop in support of learners, inventors, educators and entrepreneurs, bringing the world’s most open platform to the world’s most accessible hardware.

“In this release, we celebrate the Raspberry Pi Foundation’s commitment to put open computing in the hands of people all over the world,” said Mark Shuttleworth, CEO at Canonical. “We are honoured to support that initiative by optimising Ubuntu on the Raspberry Pi, whether  for personal use, educational purposes or as a foundation for their next business venture.”

The Raspberry Pi 2, 3, and 4 join a very long list of x86 and ARM devices certified with Ubuntu, the operating system (OS) best known for its public cloud and desktop offerings. Dell, HP and Lenovo all certify PCs with Ubuntu Desktop, which is also the most widely used OS on the AWS, Microsoft Azure, Google, IBM and Oracle clouds.

Ubuntu 20.10 also includes LXD 4.6 and MicroK8s 1.19 for resilient micro clouds, small clusters of servers providing VMs and Kubernetes on demand at the edge, for remote office, branch office, warehouse and distribution oriented infrastructure.

Ubuntu Desktop 20.10

On top of Raspberry Pi desktop support, Ubuntu 20.10 includes GNOME 3.38, which tweaks the apps grid, removes the frequents tab and allows apps to be ordered and organised however users prefer. The battery percentage display toggle has been exposed in power settings, private WiFi hotspots can be shared using uniquely generated QR codes and a restart option has been added to the status menu next to logout/power off. 

The 20.10 desktop sees added support for Ubuntu Certified devices. More Ubuntu workstations now receive biometric identification support out of the box. 2-in-1 devices with on screen keyboards are now fully supported enabling an improved Ubuntu experience on devices including the Dell XPS 2-in-1 and Lenovo Yoga.

<noscript> <img alt="" src="https://res.cloudinary.com/canonical/image/fetch/f_auto,q_auto,fl_sanitize,c_fill,w_720/https://lh3.googleusercontent.com/I7lFmpIndiuad64rxfL10k8Y36762hDUZiUn51lBLOw2iGCViFEz7oYhhVvO_xD8_NSlAkvBD8ZNfB5NbJYreLSjIq2LBxHgqcbfD9gwCQn1mZJd7jM1TMJa4YWKVBzZgSemQFX5" width="720" /> </noscript>

Raspberry Pi models with 4GB or 8GB RAM gain full support for the Ubuntu Desktop. “From the classic Raspberry Pi board to the industrial grade Compute Module, this first step to an Ubuntu LTS on Raspberry Pi with long term support and security updates matches our commitment to widen access to the very best computing and open source capabilities” said Eben Upton, CEO of Raspberry Pi Trading.

<noscript> <img alt="" src="https://res.cloudinary.com/canonical/image/fetch/f_auto,q_auto,fl_sanitize,c_fill,w_720/https://lh6.googleusercontent.com/Hy-saa5_-MtqubHuElpSKDk8QSlNWgo39f9rewwsMSnTk8acFbOAynKa8ol5Z6cDuFCsKRv8r-L8Kbome4A_LQbSB7Gmg9_rEwnzomqAGS15DZLXkBVZ7raTSp_xtn51P8fyQsS0" width="720" /> </noscript> Introducing micro clouds

Micro clouds are a new class of infrastructure for on-demand compute at the edge. Micro clouds are distributed, minimal and come in small to extremely large scale. In Ubuntu 20.10, Canonical introduces its micro cloud stack that combines MAAS, LXD, MicroK8s and Ceph on Ubuntu, to deliver resilient pocket clouds hardened for mission-critical workloads in 5G RANs, industry 4.0 factories, V2X infrastructures, smart cities and health care facilities. 

On a Raspberry Pi, users can start with MicroK8s, to orchestrate highly available workloads at the edge or with LXD to build a home lab appliance using LXD’s clustering and virtual machine management capabilities. The Ubuntu 20.10 release introduces users a way to experiment, test, or develop with full cloud capabilities through the Raspberry Pi. With Ubuntu 20.10 on a Raspberry Pi, anything is possible, from robotics to AI/ML.

Ubuntu MATE: Ubuntu MATE 20.10 Release Notes

2 days 9 hours ago

The releases following an LTS are always a good time ⌚ to make changes the set the future direction 🗺️ of the distribution with an eye on where we want to be for the next LTS release. Therefore, Ubuntu MATE 20.10 ships with that latest MATE Desktop 1.24.1, keeps paces with other developments within Ubuntu (such as Active Directory authentication) and migrated to the Ayatana Indicators project.

If you want bug fixes :bug:, kernel updates :corn:, a new web camera control :movie_camera:, and a new indicator :point_right: experience, then 20.10 is for you :tada:. Ubuntu MATE 20.10 will be supported for 9 months until July 2021. If you need Long Term Support, we recommend you use Ubuntu MATE 20.04 LTS.

Read on to learn more… :point_down:

Ubuntu MATE 20.10 (Groovy Gorilla)

What’s changed since Ubuntu MATE 20.04? MATE Desktop

If you follow the Ubuntu MATE twitter account 🐦 you’ll know that MATE Desktop 1.24.1 was recently released. Naturally Ubuntu MATE 20.10 features that maintenance release of MATE Desktop. In addition, we have prepared updated MATE Desktop 1.24.1 packages for Ubuntu MATE 20.04 that are currently in the SRU process. Given the number of MATE packages being updated in 20.04, it might take some time ⏳ for all the updates to land, but we’re hopeful that the fixes and improvements from MATE Desktop 1.24.1 will soon be available for those of you running 20.04 LTS 👍

Active Directory

The Ubuntu Desktop team added the option to enroll your computer into an Active Directory domain 🔑 during install. We’ve been tracking that work and the same capability is available in Ubuntu MATE too.

Enroll your computer into an Active Directory domain

Ayatana Indicators

There is a significant under the hood change 🔧 in Ubuntu MATE 20.10 that you might not even notice 👀 at a surface level; we’ve replaced Ubuntu Indicators with Ayatana Indicators.

We’ll explain some of the background, why we’ve made this change, the short term impact and the long term benefits.

What are Ayatana Indicators?

In short, Ayatana Indicators is a fork of Ubuntu Indicators that aims to be cross-distro compatible and re-usable for any desktop environment 👌 Indicators were developed by Canonical some years ago, initially for the GNOME2 implementation in Ubuntu and then refined for use in the Unity desktop. Ubuntu MATE has supported the Ubuntu Indicators for some years now and we’ve contributed patches to integrate MATE support into the suite of Ubuntu Indicators. Existing indicators are compatible with Ayatana Indicators.

We have migrated Ubuntu MATE 20.10 to Ayatana Indicators and Arctica Greeter. I live streamed 📡 the development work to switch from Ubuntu Indicators to Ayatana Indicators which you can find below if you’re interested in some of the technical details 🤓

The benefits of Ayatana Indicators

Ubuntu MATE 20.10 is our first release to feature Ayatana Indicators and as such there are a couple of drawbacks; there is no messages indicator and no graphical tool to configure the display manager greeter (login window) 😞

Both will return in a future release and the greeter can be configured using dconf-editor in the meantime.

Configuring Arctica Greeter with dconf-editor

That said, there are significant benefits that result from migrating to Ayatana Indicators:

  • Debian and Ubuntu MATE are now aligned with regards to Indicator support; patches are no longer required in Ubuntu MATE which reduces the maintenance overhead.
  • MATE Tweak is now a cross-distro application, without the need for distro specific patches.
  • We’ve switched from Slick Greeter to Arctica Greeter (both forks of Unity Greeter)
    • Arctica Greeter integrates completely with Ayatana Indicators; so there is now a consistent Indicator experience in the greeter and desktop environment.
  • Multiple projects are now using Ayatana Indicators, including desktop environments, distros and even mobile phone projects such as UBports. With more developers collaborating in one place we are seeing the collection of available indicators grow 📈
  • Through UBports contributions to Ayatana Indicators we will soon have a Bluetooth indicator that can replace Blueman, providing a much simpler way to connect and manage Bluetooth devices. UBports have also been working on a network indicator and we hope to consolidate that to provide improved network management as well.
  • Other indicators that are being worked on include printers, accessibility, keyboard (long absent from Ubuntu MATE), webmail and display.

So, that is the backstory about how developers from different projects come together to collaborate on a shared interest and improve software for their users 💪


We’ve replaced Cheese :cheese: with Webcamoid :movie_camera: as the default webcam tool for several reasons.

  • Webcamoid is a full webcam/capture configuration tool with recording, overlays and more, unlike Cheese. While there were initial concerns :pensive:, since Webcamoid is a Qt5 app, nearly all the requirements in the image are pulled in via YouTube-DL :tada:.
  • We’ve disabled notifications :bell: for Webcamoid updates if installed from universe pocket as a deb-version, since this would cause errors in the user’s system and force them to download a non-deb version. This only affects users who don’t have an existing Webcamoid configuration.
Linux Kernel

Ubuntu MATE 20.10 includes the 5.8 Linux kernel. This includes numerous updates and added support since the 5.4 Linux kernel released in Ubuntu 20.04 LTS. Some notable examples include:

  • Airtime Queue limits for better WiFi connection quality
  • Btrfs RAID1 with 3 and 4 copies and more checksum alternatives
  • USB 4 (Thunderbolt 3 protocol) support added
  • X86 Enable 5-level paging support by default
  • Intel Gen11 (Ice Lake) and Gen12 (Tiger Lake) graphics support
  • Initial support for AMD Family 19h (Zen 3)
  • Thermal pressure tracking for systems for better task placement wrt CPU core
  • XFS online repair
  • OverlayFS pairing with VirtIO-FS
  • General Notification Queue for key/keyring notification, mount changes, etc.
  • Active State Power Management (ASPM) for improved power savings of PCIe-to-PCI devices
  • Initial support for POWER10
Raspberry Pi images

We have been preparing Ubuntu MATE 20.04 images for the Raspberry Pi and we will be release final image for 20.04 and 20.10 in the coming days 🙂

Major Applications

Accompanying MATE Desktop 1.24.1 and Linux 5.8 are Firefox 81, LibreOffice 7.0.2, Evolution 3.38 & Celluloid 0.18.

Ubuntu Blog: Automating Server Provisioning in phoenixNap’s Bare Metal Cloud with MAAS (Metal-as-a-Service)

2 days 15 hours ago
<noscript> <img alt="" src="https://res.cloudinary.com/canonical/image/fetch/f_auto,q_auto,fl_sanitize,c_fill,w_720/https://ubuntu.com/wp-content/uploads/89f7/2020_October_Canonical-and-BMC-Blog-Post-1200x628.jpg" width="720" /> </noscript>

As part of the effort to build a flexible, cloud-native ready infrastructure, phoenixNAP collaborated with Canonical on enabling nearly instant OS installation. Canonical’s MAAS (Metal-as-a-Service) solution allows for automated OS installation on phoenixNAP’s Bare Metal Cloud, making it possible to set up a server in less than two minutes.  

Bare Metal Cloud is a cloud-native ready IaaS platform that provides access to dedicated hardware on demand. Its automation features, DevOps integrations, and advanced network options enable organizations to build a cloud-native infrastructure that supports frequent releases, agile development, and CI/CD pipelines. 

Through MAAS integration, Bare Metal Cloud provides a critical capability for organizations looking to streamline their infrastructure management processes.  

What is MAAS? 

Allowing for self-service, remote OS installation, MAAS is a popular cloud-native infrastructure management solution. Its key features include automatic discovery of network devices, zero-touch deployment on major OSs, and integration with various IaC tools. 

Built to enable API-driven server provisioning, MAAS has a robust architecture that allows for easy infrastructure coordination. Its primary components are Region and Rack, which work together to provide high-bandwidth services to multiple racks and ensure availability. The architecture also contains a central postgres database, which deals with operator requests. 

Through tiered infrastructure, standard protocols such as IPMI and PXE, and integrations with popular IaaS tools, MAAS helps create powerful DevOps environments. Bare Metal Cloud leverages its features to enable nearly instant provisioning of dedicated servers and deliver a cloud-native ready IaaS platform.   

How MAAS on Bare Metal Cloud Works

The integration of MAAS with Bare Metal Cloud allows for under-120-seconds server provisioning and a high level of infrastructure scalability. Rather than building a server automation system from scratch, phoenixNAP relied on MAAS to shorten the go-to-market timeframes and ensure excellent experience for Bare Metal Cloud users. 

Designed to bring the cloud experience to bare metal platforms, MAAS enables Bare Metal Cloud users to get full control over their physical servers while having cloud-like flexibility. They can leverage a command line interface (CLI), a web user interface (web UI), and a REST API for querying the properties, deploying operating systems, running custom scripts and initiating reboot the servers. 

“phoenixNAP’s Bare Metal Cloud demonstrates the full potential of MAAS,” explained Adam Collard, Engineering Manager, Canonical. “We are excited to support phoenixNAP’s growth in the ecosystem and look forward to working with them to accelerate customer deployments.”

Bare Metal Cloud Features and Usage

The capabilities of MAAS enabled phoenixNAP to automate the server provisioning process and accelerate deployment timeframes of its Bare Metal Cloud. The integration also helped ensure advanced application security and control with consistent performance. 

“Incredibly robust and reliable, MAAS is one of the fundamental components of our Bare Metal Cloud,” said Ian McClarty, President of phoenixNAP. “By enabling us to automate OS installation and lifecycle processes for various instance types, MAAS helped us accelerate time to market. We can now offer lightning-fast physical server provisioning to organizations looking to optimize their infrastructure for agile development lifecycles and CI/CD pipelines. Working with the Canonical team was a pleasure at every step of the process, and we look forward to new joint projects in future.”

Bare Metal Cloud is designed with automation in focus and integrates with the most popular IaC tools. It allows for a simple server deployment in under-120-seconds server provisioning, which is enabled by MAAS OS installation automation capabilities. In addition to this, it includes a range of features designed to support modern IT demand and DevOps approaches to infrastructure creation and management.  

Bare Metal Cloud Features

  • Single-tenant, non-virtualized environment
  • Fully automated, API-driven server provisioning
  • Integrations with Terraform, Ansible, and Pulumi
  • SDK available on GitHub
  • Pay-per-use and reserved instances billing models 
  • Dedicated hardware — no “noisy neighbors”
  • Global scalability
  • Cutting edge hardware and network technologies
  • Built with market proven and well-established technology partners
  • Suited for developers and business critical production environments alike

When: November 17-20, 2020

Where: KubeCon + CloudNativeCon North America 2020 Virtual Platform 

By now it’s no surprise that KubeCon NA is going virtual, like the majority of events worldwide. Is that bad news? Quite the opposite! According to CNCF, this year’s KubeCon EU – the first KubeCon to ever be hosted virtually –  made it possible for over 18,700 Kubeheads to sign up,  72% of which were first-time KubeCon + CloudNativeCon attendees. In other words, as we have all believed for so many years now, tech is helping the community grow and get closer.

So the time is approaching fast for our second virtual KubeCon, this time addressing the US, and we couldn’t be more excited! A little birdie told us the organisers are planning heaps of new things for this KubeCon, and of course so are we. Here’s a taste of what you’ll see:

Canonical showcases MicroK8s HA at KubeCon NA 2020 

Get your ticket Book a meeting

This month, Canonical made a new announcement, introducing autonomous high availability (HA) clustering in MicroK8s. This gives MicroK8s the added benefit of full resilience for production workloads in cloud and server deployments.

Designed as a minimal conformant Kubernetes, MicroK8s installs and clusters with a single command. 

Want to see it in action? We’re excited to show you! Feel free to pre-book a meeting with one of our engineers using the button below, or keep reading for more on our next section. 

Already popular for IoT and developer workstations, MicroK8s is one of Canonical’s two Kubernetes distributions. One of the many reasons Canonical’s lightweight Kubernetes has gained so much community attention? You can install MicroK8s on any device in under a minute

High availability is enabled automatically once three or more nodes are clustered, and the data store migrates automatically between nodes to maintain quorum in the event of a failure. “The autonomous HA MicroK8s delivers a zero-ops experience that is perfect for distributed micro clouds and busy administrators”, says Alex Chalkias, Product Manager at Canonical.

Ubuntu Blog: OpenStack at 10 – from peak to plateau of productivity

2 days 22 hours ago
<noscript> <img alt="" src="https://res.cloudinary.com/canonical/image/fetch/f_auto,q_auto,fl_sanitize,c_fill,w_720/https://ubuntu.com/wp-content/uploads/80ca/OpenStack-Logo-Horizontal.png" width="720" /> </noscript>

This week is the latest Open Infrastructure Summit, in a week where the OpenStack Foundation became the Open Infrastructure Foundation to reflect the expansion of the organisation’s mission, scope and community to advance open source over the next decade to support open infrastructure. It is also ten years since OpenStack launched and a lot has changed during that time. 

We asked freelance journalist, Sean Michael Kerner, to share his views on the last ten years. Sean is a freelance journalist writing on myriad IT topics for publications around the world. He has spoken at more OpenStack events than he cares to remember. English is his second language (Klingon his first). Follow him on Twitter @TechJournalist.

10 years ago in July 2010, I got an unusual pitch from a PR person. It was the beginning of a long and winding road that defines my experience and viewpoint on OpenStack.

Unlike the usual spate of product and open source pitches from vendors that I got at the time (and still get), the pitch I got on the sunny July afternoon was an offer to speak with the CTO of IT at NASA. It was an offer I couldn’t refuse – and I suspect it’s also the reason why OpenStack got so much attention early on – it was literally ‘rocket science’. In a 2012 video interview I did with Chris Kemp after he left the role of CTO at NASA to start his own OpenStack startup, he told me that in his view OpenStack could well become one of NASA’s great contributions to society.

That was the early hype cycle, and it was amazing to watch. From the early days of just two vendors in 2010, to the heady days of 2012 and the San Diego summit where analysts (and yours truly) were in awe of the rapid embrace of OpenStack by large IT vendors.  A year later in 2013 at the Portland summit, I remember clearly being approached by a venture capitalist after an analyst panel. The VC wanted to know who I thought they should invest in. There was a board of sponsors and vendors mounted against the wall and I told him without hesitation – in five years half the vendors would be gone – I wasn’t wrong.


While I’ve written more than my fair share about the ‘hype’, my interest in OpenStack has been about the technology, the processes that make the project work and the people that bring it all together.

Much like the early explosion of vendors, OpenStack had a rapid acceleration of projects in the early days. It started with just Nova for compute and Swift for storage. Then with each successive release, more projects came in, Keystone for identity, Glance for images, Quantum/Neutron for networking and so on. The OpenStack Foundation struggled in those early days to define what OpenStack actually was all about – there were efforts like Refstack which was an attempt to define a reference implementation and other efforts. There was also the ‘Big Tent’ – an idea where lots of different ideas and projects could all cohabitate under the OpenStack umbrella.

At one point, I could name every project in the OpenStack family – then one day I couldn’t. Did OpenStack bite off more than it could chew? Take on more projects than anyone could use? Aim to be all things to all people when not all people needed all things? … Maybe.

In 2019, at the OpenStack Summit in Denver, which was the first branded as the Open Infrastructure Summit, the halls were quiet and it was the first where I remember there being fewer people than any prior event. The hype was gone, but the core technology remained.

It Was Never Really OpenStack vs AWS

In the early days of OpenStack there was an idea and perhaps an expectation from some that most enterprises wanted or needed to build their own private clouds. There was also a hope that service providers would embrace OpenStack to build public cloud offerings that would effectively challenge or perhaps even surpass AWS.

That’s not what OpenStack is today – or where it ever really was – even if that’s what Rackspace wanted it to be. OpenStack is about open infrastructure and it’s fitting that now that’s also the rebranded name of the OpenStack Foundation.

10 years after first engaging with OpenStack, I have every expectation that it will still be around 10 years from now. OpenStack, though it has gone through the ‘trough of disillusionment’ is now firmly headed toward the ‘plateau of productivity’ at the end of the Gartner hype cycle.

We’re still talking about OpenStack 10 years later because it’s still useful.  We’re still talking about OpenStack because it hasn’t stood still, it has continued to evolve and it’s a technology that still matters. In the final analysis, technology survives if it can adapt to the actual needs of the market and that’s something that vendors like Canonical have long recognised. Among the many interviews I’ve had the privilege of doing with Mark Shuttleworth at OpenStack events over the years was the Barcelona Summit in 2016.

“There is no shortage of truly terrible ideas in OpenStack; it’s a truly open forum, with very little leadership and a lot of governance,” Shuttleworth said at the time. “OpenStack needs to focus on stuff that matters.”

And so it has.

Ubuntu Blog: Telco cloud: what is that?

2 days 23 hours ago

Telco cloud or a network function virtualisation infrastructure (NFVI) is a cloud environment optimised for telco workloads. It is usually based on well-known technologies like OpenStack. Thus, in many ways, it resembles ordinary clouds. On the other hand, however, it differs from them. This is because telco workloads have very specific requirements. Those include performance acceleration, high level of security and orchestration capabilities. In order to better understand where those demands are coming from, let’s start with reviewing what kind of workloads are telcos running in the cloud.

Telco workloads in the cloud

Have you ever been wondering how the telecommunications infrastructure works? You probably have not, but do not worry, you are not the only one. All we usually care about today is a stable Internet connection. Understanding how does it work is of secondary importance. However, behind a network socket or your Wi-Fi router, there is a massive infrastructure which provides this connection. It consists of thousands of interconnected services, including firewalls, base transceiver stations (BTS) for providing mobile connection, voice and data aggregation systems, etc.

<noscript> <img alt="" height="267" src="https://res.cloudinary.com/canonical/image/fetch/f_auto,q_auto,fl_sanitize,c_fill,w_267,h_267/https://ubuntu.com/wp-content/uploads/0fc2/icon-1000px.png" width="267" /> </noscript>

Historically, all of those services used to be implemented in hardware. Nowadays, however, service providers are moving to software-based network services. The migration is driven by economical benefits resulting from better utilisation of resources in cloud environments. As software-based network services are implemented on top of virtual machines (VMs) or containers, service providers can simply run them in a cloud, benefitting from lower operational costs and improved agility. Such a telco cloud, however, must meet certain criteria before network services can be deployed on top of it.

Telco cloud under the hood

In order to implement a telco cloud, service providers can use either proprietary or open source technologies. Over the past few years, it has been concluded that for the open source telco cloud implementation OpenStack will be used as the basis. What makes the telco cloud different from an ordinary OpenStack cloud, however, are very specific features required by telco workloads.

<noscript> <img alt="" height="157" src="https://res.cloudinary.com/canonical/image/fetch/f_auto,q_auto,fl_sanitize,c_fill,w_254,h_157/https://ubuntu.com/wp-content/uploads/a064/Screenshotfrom2018-09-0310-33-04.png" width="254" /> </noscript> Performance

Among various metrics, performance results are what telcos care the most. This is because telco workloads are network-heavy. They have to process up to 100 Gb per second. Thus, it is important that telco workloads achieve comparable performance results regardless of whether they are implemented in hardware or in software. This is challenging, however, as VMs usually cause performance degradation. In order to solve this problem telco clouds implement a bunch of performance extensions, such as single-root input/output virtualisation (SR-IOV), data plane development kit (DPDK) or central processing unit (CPU) pinning. All of that allows software-based network services to achieve performance results comparable to those achieved by physical machines.


Another important aspect is security. Telcos are known for being security-oriented. Thus, the telco cloud must provide a desired level of security too. Service providers usually achieve that by applying hardening on the operating system level. Hardening is a process of securing the system by reducing potential vulnerabilities to an absolute minimum. This is achieved by disabling unnecessary services, narrowing down permissions, closing open ports, etc. For obvious reasons, telco cloud is also deployed on-prem in most of the cases. The security team can later use standard technologies, such as packet inspection or data encryption to secure the telco cloud at each layer of the infrastructure stack.


Last but not least orchestration is what characterises the telco cloud as well. Although orchestration is a broader term in general, it is especially important in the case of telco workloads. This is because software-based network services are usually very complex. They consist of multiple interconnected components (network functions) which are often distributed across multiple substrates. Thus, having a tool which can arrange resources, deploy network services and maintain them post-deployment is important for service providers. Among various proprietary and open source solutions, an Open Source MANO (OSM) project has recently been getting momentum, enabling telcos with management and orchestration (MANO) capabilities.

Telco cloud on Ubuntu

Canonical is an established leader in the field of implementation cloud environments for telcos. Over the past few years, the company has successfully onboarded leading global and national tier-1 service providers like AT&T, BT or Bell on their open source NFVI platform based on Ubuntu Server, Charmed OpenStack and Charmed Ceph. With an increasing demand for cloud-native network services Canonical also stands by ready to offer Charmed Kubernetes as an extension of the underlying cloud platform. Finally, as workloads orchestration becomes the biggest challenge in the telco world nowadays, the company provides Charmed OSM to enable service providers with these capabilities.
