Public bug reported: Finally, almost when the next release becomes available, I’m given the chance to upgrade from 24.04 to 26.04. Ok, let’s go ahead…except it refuses to. I get this error saying it can’t “calculate the upgrade” and it closes out. Retrying does no good of course. The log files don’t seem very revealing to me.
