Perhaps if I had preempted such trouble and configured a password for root?

Quite possibly. Anyway there was an easy GUI thing.

Well I'm kind of invested in it now (some degree of vendor lock-in). The
reason I used it in preference to Debian was its Long Term Support which
made me feel warm and fuzzy. Still kinda does.

It's nice to know though that if push came to shove I could escape to
Debian (although I don't know if I'd run 'testing' or something else,
that would be a question for you!).

That Salt Stack is currently unsupported on 20.04 is starting to become
a problem for me. I'd like to upgrade my 10.04 systems but I can't
because I rely on Salt Stack being available.
