[Bug 2009643] [NEW] Could not calculate the upgrade

[Hangyeol Jeon]

Public bug reported:

Tried to upgrade Ubuntu 20.04 to 22.04, and got this error:


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 tried to unselect everything in Software & Updates - Other Software
tab, and that did not help me.
