[Bug 1902767] Re: do-release-upgrade exits with "An unresolvable problem occurred while calculating the upgrade"

[Rich Stillman]

Thanks. I eventually removed enough packages from the system to allow the
upgrade to work. It was a long time ago so I don't remember the details
anymore and I think I threw out my notes.

Since then, apt upgrades, including kernel upgrades, have been working
fine.

Just one more year, and we get to do this all over again...
