[Bug 1990967] [NEW] Could not calculate the upgrade when upgrading to Ubuntu 22.04

[Guillaume Marchand]

Public bug reported:

Current Ubuntu version Ubuntu 20.04.5 LTS
Would like to upgrade to Ubuntu 22.04 but I have the following error message 

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.

when I check the main.log I have no package listed as foreign and some
as obsolete

MetaPkgs: ubuntu-desktop

pa-0.2-bluetooth libspa-0.2-modules microsoft-edge-stable pipewire-alsa pipewire-audio-client-libraries pipewire-bin pipewire-jack pipewire-locales pipewire-media-session pipewire-pulse zoom

On which PPA should I run ppa-purge? Any advise?

Thanks
