Hello John,
There was a method - I believe a letter used during installation that provided logs, but I can't find how to get to it.
I'll give Debian 11.1 one more try since I didn't know the switch or method which I did use in the past, I've just forgotten.
Is it "a" for advanced? and then it is "a", something further down the installation, something tells you how to save and report bugs, I truly forget how to do what I did before.
I cannot find it, it is doubtless there, but I'm not lucky enough to see and hear what's in front of me sometimes.
Best wishes,
David
