It's unfortunate that the AMD installer doesn't clean up properly after itself. You should file a bug with AMD for that.
It might also be a good idea to check the source of all of your installed packages to make sure there are no other non-Ubuntu packages that might interfere with the rest of the system. Mesa looks to be a likely candidate. I'm sure there are better ways to do this but here's a quick and dirty command to help with that: $ dpkg -l | awk '{print $2}' | xargs apt-cache policy | grep -E -A1 '^\S|\*\*\*' -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2080823 Title: 6.8.0-44 breaks amdgpu-dkms 6.8.5 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2080823/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
