[Bug 2086128] [NEW] Upgrade failed without indication of the reason

[Chris Rudi]

Public bug reported:

I can't upgrade (20.04 to 22.04) because the do-release-upgrade comes up
with :

Could not calculate the upgrade

An unresolvable problem occurred while calculating the upgrade.

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'.

I have deactivated the third party ppa
