Thank you for taking the time to report this bug and helping to make Ubuntu better.
Bug reporting is mostly about finding & fixing problems thus preventing future users from hitting the same bug. I suspect a Support site would be more appropriate, eg. https://answers.launchpad.net/ubuntu. You can also find help with your problem in the support forum of your local Ubuntu community http://loco.ubuntu.com/ or asking at https://askubuntu.com or https://ubuntuforums.org, or for more support options please look at https://discourse.ubuntu.com/t/community-support/709 (I haven't looked far, but I see reference to a PPA that has no support for any release past 14.04; ie. https://launchpad.net/~tualatrix/+archive/ubuntu/ppa PPA's are 3rd party sources, so all security checks are the responsibility of the end- user; and a PPA that doesn't support releases later than 14.04, was last touched in 2014 is a warning sign that it should not be touched) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1931863 Title: Upgrade from 18.04 LTS to 20.04.2 LTS impossible To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1931863/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
