[Bug 2022381] [NEW] Ubuntu 20.04 to 22.04 update bug.

[Eugene]

Public bug reported:

I'm trying to update from ubuntu 20.04 to ubuntu 22.04 and I'm
enconutering the following error.

Could not calculate 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. 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'.
