[Bug 2046668] [NEW] Upgrade to 23.10 fails with error 'unresolvable problem...'

[Walders]

Public bug reported:

Upgrade to 23.10 fails with an error:

"
Calculating the changes

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 been unable to identify the broken packages, and unable to fix
from solutions offered in other message boards.
