That might be the issue, but trying to remove the ROS URL from 'Other Software' along with the PPAs I thought it was originally still doesn't work so trying to upgrade fails, presumably because they're not being properly removed. I've tried using the ppa-purge tools too but not sure how to get that to work for the ROS packages since they're not listed as ppa in the 'Other Software' tab. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1891683 Title: Focal upgrade doesn't work, unable to remove the 'peek' ppa To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1891683/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
