[Bug 2038251] [NEW] updating from Ubuntu 22 to 23.04 fails (shim-signed broken?)

[Dave LeCompte]

Public bug reported:

I am trying to upgrade to 23.04, either by GUI or command line. I get a
message that it can't calculate the upgrade, without any instructions of
diagnosing why.

I looked at broken packages, and I see that shim-signed is saying that
it's broken. I've tried reinstalling it, but upgrades still don't work.
