upgrade to 22.04.5 fails, "unable to calculate upgrade"

[Rob Ropes]

It appears that a third party piece of software is preventing the upgrade from working. I went through the log files and could not identify anything obvious (I don't know what I'm looking for in the files). I've tried the upgrade a couple of times with the same result. Is there some way to to identify the cause of the problem more precisely?
