  • It will also be possible to upgrade from Linux Mint 21.

Bug reports:

  • Bugs in this release should be reported on Github at
  • Create one issue per bug.
  • As described in the Linux Mint Troubleshooting Guide, do not report or create issues for observations.
  • Be as accurate as possible and include any information that might help developers reproduce the issue or understand the cause of the issue:
    • Bugs we can reproduce, or which cause we understand are usually fixed very easily.
    • It is important to mention whether a bug happens “always”, or “sometimes”, and what triggers it.
    • If a bug happens but didn’t happen before, or doesn’t happen in another distribution, or doesn’t happen in a different environment, please mention it and try to pinpoint the differences at play.
    • If we can’t reproduce a particular bug and we don’t understand its cause, it’s unlikely we’ll be able to fix it.
  • The BETA phase is literally a bug squashing rush, where the team is extremely busy and developers try to fix as many bugs as fast as possible.
  • There usually are a huge number of reports and very little time to answer everyone or explain why a particular report is not considered a bug, or won’t get fixed. Don’t let this frustrate you, whether it’s acknowledged or not, we appreciate everyone’s help.

  1. Hi folks. TYPO on New Features page
    The caption “Duplicating a note in Sticky Notes” is with the illustration for Software Sources change.

    And… you’re going to get a lot of stick for the theme changes. I must say you should. This does not work. Please give us more on-surface reversion options. Make them simple, and complete. People setting up a new box don’t like getting stuck with a tar baby with this stuff. …and please that rainbow spinner really needs to go. And the ‘modern’ arrow? That’s what’s in the menu for UT2004… and that colour-choser in the Welcome — that is a really great idea, but always have a Cancel / Undo with this sort of feature. (oh dear, I’m in the other tar pit. Thank you for the new release! Otherwise excited & happy.

  2. Upon testing, it seems very hard to keep the look of Mint-Y-as-in-20.3-to-21. I like Mint-Y’s current title bar (both the size and the maximize/unmaximize icon) but not the new saturated green colour. Looks like I am going back to Mint-Y-Legacy for Controls. I like the non-darkened left panel in Caja more but this is minor and miles better than staring at the uncharacteristic blue highlight or the over-saturated green highlight accent.

    I haven’t decided if I will go back to Mint-Y-Legacy for icons too but I am testing the beta in VM, not production computer yet. So this can wait.

    1. … But after I choose Mint-Y-Legacy for Controls, the title bar buttons in CSD applications follow the Legacy theme too and ignore the choice in Window Border. Argh!

      So I still have to experiment in creating custom theme at the end, just for the right blend of “old” look.

    1. Maybe it’s only a Cinnamon feature? I installed Vera Mate (the stable version approved yesterday) and try a right-click on the last Vera’s iso and nothing! no “Verify” option in the contextual menu.

    2. Verify works fine for me with 21.1 Beta. Won’t work if the .ISO is saved to the desktop. I had to move it to Downloads.

    3. I successfully used Verify from the installation of Mint Mate 21.1 beta to verify the the ISO of the recent final release of Mint 21.1. I have not tried to verify the ISO of any of the earlier Mint versions and I have not installed the final release of Mint Mate 21.1 to see if Verify works from there.

    4. I have now installed the final release of Mint Mate 21.1 on an SSD. When I right click on the ISO for 21.1 from within CAJA, I DO NOT get an option to Verify. However, I installed Nemo and when I right click on the ISO from within Nemo I DO get an option to verify the ISO. At this point, the verify function indicates the correct SHA256sum but gives me a message that the SHA256sum file does not contain sums for this ISO image. This ISO was previously fully verified and based on my experience, I suspect that if I download a new copy of the ISO it will verify correctly. So I think the Verify function needs more work! I don’t really care very much anyway – I haven’t worried about the checksum for several years.

  3. First, a big thank you for all the work you put into this!

    So the other day I was trying out the performance of a virtual machine, running Mate 21 and while the installer was doing as usual, everything looks fine but- the installer also suggests you install the media-codecs.
    And this is my question, for what purpose?
    I have been using Mint since the Katya release from eons ago but after only installing those codes once in all that time, I asked myself, why the installer seems adamant to get those codecs installed?
    There must be something else that gets installed amongst those codecs.
    I am not asking what it is that makes it so important, I am asking what app requires those codecs?
    My main multimedia app is MPV, which has the entire ffmpeg library already compiled in, VLC uses it’s own libs as well, Celluloid uses the MPV libs and options and the SMPlayer looks for the ffmpeg libs and codecs.
    Should you don’t have ffmpeg installed, it uses the MPV ones. Even Audacity works just fine
    None of them ever complained that the mint-media-codecs weren’t installed, so I never did, after that one first time. Unless I am completely disregarding something not apparent, but important for another purpose.
    As far as I can tell, nothing seems missing or broken because of it. So far that covers 90%-ish of all the media they people watch and listen to with the mentioned programs..
    All the websites seem to be just fine, NetFlix, Diesney+, AmazonPrime and the youtube play their content with FireFox and without the cocecs being installed. What am I missing?

  4. Reading package lists… Done
    E: The repository ‘ vera Release’ does not have a Release file.
    N: Updating from such a repository can’t be done securely, and is therefore disabled by default.
