Upgrade to 22.04 fails

[Kevyn Pair]

An unresolvable problem occurred while calculating the upgrade.

 This was likely caused by:
 * Unofficial software packages not provided by Ubuntu
Please use the tool 'ppa-purge' from the ppa-purge
package to remove software from a Launchpad PPA and
try the upgrade again.

If none of this applies, then please report this bug using the command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal. If you want to investigate this yourself the log files in '/var/log/dist-upgrade' will contain details about the upgrade. Specifically, look at 'main.log' and 'apt.log'.

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!
