Thank you for taking the time to report this bug and helping to make Ubuntu better.
The tool was made to upgrade Ubuntu and flavors of Ubuntu (https://ubuntu.com/download/flavours) where as you are not use a supported system. Your system has foreign (Pop) packages that the upgrade tool wants to remove to accomplish upgrade, but your system has marked as 'cannot be removed' 2021-06-14 13:27:39,901 DEBUG The package 'pop-desktop' is marked for removal but it's an ESSENTIAL package 2021-06-14 13:27:56,093 ERROR Dist-upgrade failed: 'The essential package 'pop-desktop' is marked for removal.' The issue is not the upgrade tool but you're using an unsupported product; ie. not using a Ubuntu system. Please refer to Pop OS documentation, eg. https://support.system76.com/articles/upgrade-pop/ I've marked this 'invalid'; however if you believe I'm in error, please leave a comment explaining why, and the status can be changed back to "New". ** Changed in: ubuntu-release-upgrader (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1931905 Title: Crash on upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1931905/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
