Thank you for taking the time to report this issue and helping to make Ubuntu better.
You have a number of 3rd party packages that are stopping the upgrade, eg. mesa-vdpau-drivers:amd64 (21.2.0~rc3+git2108022230.58bf0165ca0~b~mesarc5) which has a package ver. that prevents upgrade to focal. Please remove your 3rd party (Unofficial software packages) using a tool like 'ppa-purge' from your PPA's and try again. I've marked this incomplete, as third party packages from PPAs have prevented the upgrade; the upgrade tools are intended to work with Ubuntu repository software only. If you believe I'm in error, please leave a comment explaining why and you can return the status to "New". ** Changed in: ubuntu-release-upgrader (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1938889 Title: unable to upgrade to 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1938889/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
