Public bug reported: My upgrade from Xubuntu Studio Artful Aardvark to Bionic Beaver failed early in the configuration stage, with no explanation. I repaired with ""apt --fix-broken installation" and seem to have a working system now. A lot of automatic problem reports were generated, and I have no idea what caused them.
