It's almost the end of March 2021 - spring flowers and April showers are on the horizon! And so is the release of ** Ubuntu MATE 21.04 (Hirsute Hippo)!**
Thank you to everyone who has helped us with previous testing for 21.04, including the initial ISOs.
We can't say enough how important the community contributions are during these testing periods.
We're getting together with Ubuntu and the other flavors for another testing week, and as you know, team work makes the dream work! This testing week is focused on the Beta release on April 1, which is no joke! Final release is four weeks away, on April 22. 21.04 is an interim release, and will be supported until January 2022.
If you want to share in the excitement on social media, please use the hashtag #UbuntuTestingWeek. Ubuntu and all the flavors are all one community, and if you're able to help out other flavors, it helps all of us make awesome things.
And if you've been nervous about testing, now is a great time to ask for help and join in! Chat with other testers on IRC (#ubuntu-quality on Freenode) or Telegram (Ubuntu Testers). Testing doesn't require any coding knowledge, can take as little as 30 minutes to complete a test case and file a report, and can be done on a VM or bare metal with a spare machine.
Directions and helpful hints are below, and if you have any questions, please reply to this post!
You can find the test ISO here :
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!
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.
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.
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
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!
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! If you rely on your system as your daily driver, it might be advisable to wait for the final release.
Friendly reminder that developmental releases HAVE the possibility of breaking and requiring a reinstall. So please keep that in should you choose to run it as your daily driver.
To upgrade, press Alt + F2, and type:
If you aren't prompted to upgrade, press
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.'
