Canonical announces full enterprise support for Kubernetes 1.21
by Paul Hill
Canonical, the firm behind the Ubuntu operating system, has announced full enterprise support for Kubernetes 1.21. It said that support ranges from public cloud to edge and covers Charmed Kubernetes, MicroK8s, and kubeadm. According to Canonical, MicroK8s is suited for workstations, DevOps, edge and IoT, Charmed Kubernetes is aimed at multi-cloud clusters, and kubeadm is designed for manual operations.
Notable changes in Kubernetes 1.21 include a memory manager which will improve the performance of some applications, new scheduler features, improvements to ReplicateSet downscaling, support for indexed jobs, and the deprecation of Pod Security Policy before its complete removal in Kubernetes 1.25.
Commenting on the launch of Kubernetes 1.21, Canonical Product Manager Alex Chalkias said:
Enterprise support for Kubernetes on Ubuntu is provided by Canonical as a part of the Ubuntu Advantage for Infrastructure (UA-I) support subscription. The package includes long-term security maintenance, kernel Livepatching, and mission-critical infrastructure support for the full stack from the kernel to the container across public clouds, Vmware, OpenStack, and bare metal.
In terms of product releases from Canonical, this month is turning out to be a bit busy. On the first day of the month, Canonical launched Ubuntu 21.04 beta and is intending to release the finished product on April 22.

Canonical releases Ubuntu 21.04 Hirsute Hippo beta
by Paul Hill
Canonical has announced the availability of Ubuntu 21.04 Hirsute Hippo beta for Desktop, Server, and Cloud. There are also downloadable beta images of alternative Ubuntu flavours including Kubuntu, Lubuntu, Ubuntu Budgie, UbuntuKylin, Ubuntu MATE, Ubuntu Studio, and Xubuntu.
The main Ubuntu 21.04 for Desktop is quite a good release this time around; it includes the newer 5.11 Linux kernel so more hardware will be supported and Canonical has switched to Wayland sessions by default away from X.org. Unlike Fedora 34, Canonical has decided to stick with GNOME 3.38 so that it can adapt its desktop extensions to work properly with GNOME 40.
In its announcement, Canonical said:
If you’d like to take Ubuntu 21.04 beta for a spin before the final release drops on April 22, head over to the mailing list announcement where you can find the links to all of the available Ubuntu 21.04 beta editions and flavours. Keep in mind that this software is still in development and you could run into bugs. If you do, you can report them to Canonical so they can be fixed before the final release later this month.

Canonical releases second point release of Ubuntu 20.04 LTS
by Paul Hill
Canonical has announced the availability of Ubuntu 20.04.2 LTS – the second point release for Ubuntu 20.04 LTS. As with other point releases, Canonical has spun a new ISO that includes all the security and software updates and it comes with the latest hardware enablement stacks so that newer hardware works properly.
Ubuntu 20.04.2 LTS is available for the Desktop, Server, and Cloud products as well as other flavours of Ubuntu such as Kubuntu, Ubuntu Budgie, Ubuntu MATE, Lubuntu, Ubuntu Kylin, Ubuntu Studio, and Xubuntu. If you want to download any of the Ubuntu products or the spins, head over to the Ubuntu downloads page and find what you want.
According to the Ubuntu 20.04 release notes page, Ubuntu 20.04.2 LTS ships with the Linux 5.8 kernel instead of Linux 5.4 which was the original kernel shipped last April when Focal Fossa came out. Those installing Ubuntu Server will have to opt-in to using the new kernel through the installer bootloader as it’s not the default choice.
As with all Ubuntu LTS releases, you should expect security and software updates for five years until the first half of 2025. The derivative flavours are an exception, however, receiving support for just three years.

Canonical launches Ubuntu Core 20 for IoT devices
by Paul Hill
Canonical has announced the general availability of Ubuntu Core 20, a stripped back version of Ubuntu 20.04 LTS designed for IoT devices and embedded systems. According to the company, this update improves device security with the inclusion of secure boot, full disk encryption and secure device recovery.
Ubuntu Core is available for many popular x86 and ARM single board computers making it pretty accessible. IoT devices are not always easy to update so Canonical has configured Ubuntu Core to provide automated and reliable updates out of the box so end users don’t need to worry about updating their devices. While an LTS is usually supported for five years, it provides business-critical devices with 10 years of support.
Commenting on today’s launch CEO Mark Shuttleworth said:
Probably the most familiar device that can run Ubuntu Core, is the Raspberry Pi Compute Module. If you have a Raspberry Pi Compute Module or other compatible device lying around you can get it to work with Ubuntu Core 20 by heading over to the IoT section of the Ubuntu website and scrolling down to Ubuntu Core.

Ubuntu 21.04 will use Wayland display server by default
by Paul Hill
Canonical’s Sebastien Bacher has announced that Ubuntu 21.04 will ship with the Wayland display server as the default, replacing X.Org. Bacher confirmed that NVIDIA users will still default to X.Org due to some on-going issues but the company hopes that these will be fully resolved by the time of the next Ubuntu LTS release in April 2022.
If any of this sounds familiar, it’s because Canonical actually set Wayland as the default in Ubuntu 17.10 almost four years ago but found that the software was not ready to be released in the then-upcoming Ubuntu 18.04 LTS which would be used on production machines. Since then, other distributions have adopted Wayland and bugs have been worked out enough so that Canonical is ready to give it another shot.
Explaining the situation, Bacher said:
By shipping Wayland with Ubuntu 21.04, the company has a whole year and another Ubuntu release in October to find any major issues and get them fixed. This additional time, compared to when it was attempted before, should be long enough to ensure a stable Wayland release with Ubuntu 22.04 LTS.
