[Bug 1988350] Re: Impossible to upgrade from Ubuntu 20.04 LTS to 22.04 LTS

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!

Title:
  Impossible to upgrade from Ubuntu 20.04 LTS to 22.04 LTS

Status in ubuntu-release-upgrader package in Ubuntu:
  Invalid

Bug description:
  do-release-upgrade failed to upgrade with

  Calculating the changes

  Could not determine the upgrade

  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. 

  But there are no ppa to purge.
