do-release-upgrade to jammy fails

[Connor Kelly]

Upgraded all packages and performed an autoremove. When attempting to upgrade to jammy do-release-upgrade failed. It told me I needed to remove a ppa but wouldn't tell me which one. The main.log appears to point to ubuntu-desktop. I re-installed it but it failed on a second attempt

Reviewing the files from your upgrade attempt, you have installed pipewire packages from the pipewire-debian/pipewire-upstream PPA. Some of the packages installed are newer than those in the official archive, which is keeping some pipewire-related packages installed which then prevents the upgrade from being calculated. Please try using the ppa-purge tool to remove packages installed from ppa:pipewire-debian/pipewire-upstream. After that you can try upgrading again and if it still fails open a new bug report. Thanks and good luck!
