[xubuntu-users] cannot upgrade from 20.04 to 22.04

[Jonathan]

Hello,

I have a problem upgrading XUbuntu from version 20.04.6 to version 22.04 LTS.
The updater always dies at the stage of "calculating upgrade..."
Sometimes it dies with no error message; other times I get ""

I have posted detailed debug logs on the official Ubuntu support forum,
https://answers.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+question/703016

The person who responded on the official Ubuntu support forum walked me through extensive troubleshooting and then concluded:

"What puzzles me most is that the upgrader tries to remove the xubuntu-core package and then claims that it is missing.
I have no experience with xubuntu, so I do not know what's so specific on the xubuntu-core package and its dependencies that it breaks the upgrade."

He then referred me to XUbuntu-specific support.

In its current state, when I run Software Updater to install the latest security patches, I get a prompt saying that "Not all updates can be installed.  Run a partial upgrade, to install as many updates as possible.  This can be caused by: A previous upgrade which didn't complete..." so I try to run a partial upgrade, but then I the updater freezes.  Please see attached screenshot of frozen dialog box.

Thank you,
Jonathan
