Ubuntu MATE 21.04 Testing

Happy New Year! :fireworks:

It's 2021 and that means a new Ubuntu release will be coming SOON, so it's time for Ubuntu MATE 21.04 (Hirsute Hippo) Testing! :bug:

Along with Ubuntu and the other Ubuntu flavors, Ubuntu MATE 21.04 is now ready for testing. Thank you to everyone who tested the initial 21.04 ISOs, and it can't be stated enough how important the community contributions are during these testing periods. :raised_hands:


Preliminary Hirsute Hippo Release Notes

21.04 Hirsute Hippo is an interim release, with support through January 2022.

  • Scheduled for release April 22nd

You can find the test ISO here, and we will update when the tracker gets a direct beta link :floppy_disk: :

You can test on either a spare machine or a virtual machine, and please let us know in this thread if you encounter any problems. If at all possible please file Bug reports. The sooner we know about a problem, the sooner we can tackle it! :clock11:

If you’re new to ISO testing, or need a refresher, here’s a quick guide:

First of all, you’ll need a Launchpad/Ubuntu One login. Go here to create one if you haven’t done so already.

You’ll want to download the Hirsute Hippo daily build here: http://cdimage.ubuntu.com/ubuntu-mate/daily-live/current/

Take a look at the testsuites for Ubuntu MATE, many of which take less than 30 minutes to complete. :clock1030:

Follow the directions in the testsuite. If it does all of those things, great! If it doesn’t, however, we need your help. Click on the link at the top of the page that reads “Report a bug against the contents of this testcase.” Sign in with your Launchpad/Ubuntu One account.

Follow the directions in the bug report, and be as specific as you can! This is a key step - an unreported bug will be an unfixed bug. :bug: :receipt:

While we don't have have the Ubuntu MATE 21.04 Release Notes available at this time, we will update this page once they are online.

There have been several updates to Ubuntu MATE packages for release in 21.04 as well as the underlying Ubuntu base packages. There are some major changes coming in this release, in addition we would like some testing focus on:

  • AMD GPU issues
  • Arctica-greeter

Early testing and bug reporting will help improve the final release.

Thank you again for testing and for reporting your issues, concerns, observations, and questions in this thread! :green_heart:

You can upgrade to the developmental release using the instructions below. However we encourage testers to try the daily ISOs as much as possible. We recommend anyone who upgrades their system to the developmental version to backup first! :harddrive: If you rely on your system as your daily driver, it might be advisable to wait for the final release.

:stop_sign: Friendly reminder that developmental releases HAVE the possibility of breaking and requiring a reinstall. So please keep that in :brain: should you choose to run it as your daily driver. :stop_sign:

To upgrade, press Alt + F2, and type:

update-manager -cd

If you aren't prompted to upgrade, press Alt + F2 again, then


and click Settings and Livepatch. Go to the Updates tab and toggle the option for 'Notify me of a new >Ubuntu version' to 'For any new version.'

Press Alt + F2 again, and then type:

update-manager -cd

About arctica-greeter we already have bug 1910279. It needs reaction from upstream.

UM 21.04 desktop testing maybe partially done by using X11 Docker containers.

ISO testing maybe done by running them in VirtualBox or in QEMU with quickemu.
