 Btw, X or  X Window System - never X Windows.

 Interesting.  You should have been able to login as root from the console,

 On OSX that's still just 'dd', isn't it?

I found this thing called Ubuntu Core 18. Hadn't heard of that before.

 Why do you still trust and use Ubuntu?

 Is this just Raspbian?  I think perhaps it is.

 Raspbian is basically Debian, but (at least originally) with a modified
kernel, from back in the old days when a standard kernel simply wouldn't
run on the early model Pis.

 Now the distinction is probably even more subtle - some binary blobs that
Debian (DFSG) wouldn't agree with, but I suspect almost everything else
looks and smells close to pure.  I've never hit any problems with Raspbian
that have motivated me to explore alternative distributions.  Not that I
really push the use case boundaries of any of my Pis.

 Oh, I should perhaps identify my Kodi / OpenElec Pi as an exception -
though I now think of that more as a black box appliance than a computer
running GNU/Linux + tools.

 And Home Assistant (which I'm not actually running currently, so that's
easier to overlook).
