[Bug 1991575] Re: while upgrading to 22.04 it complains of "unrecoverable error"

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 by running ppa-purge -s ppa.launchpad.net -o
pipewire-debian -p pipewire-upstream. After that you can try upgrading
again and if it still fails open a new bug report. Thanks and good luck!
