That reads as though it would need intervention from me after every
screen. I do not think that would help. See below.

I meant that.
The disk drive was locked, The screen was black. The keyboard did nothing.

No response from keyboard! Not even with "Alt+SysRq+<S,U,S,U,B>".

That was what the computer said after I did the unthinkable and pulled
the plug out. Did not help me, because I did not know which lock file.

I had read that a fluctuating connection to the Internet can cause
disaster during a "dist-upgrade". It is one of the reasons why I had not
taken this route seriously.
I could have looked at the script that recorded everything that happened
during the "dist-upgrade". But I was too discouraged (and probably lack
the know-how to fix the problem).

I normally shut down everything and run "apt-get" routines from a
console. I could not work out how to get to the console after the
changed format that was delivered by the (successful) boot into Squeeze;
so I settled for using an xterm - and lived to regret that decision!

My guess is quite different.
I blame the "xscreensaver" routines, some of which may have been
mutilated during the uncompleted upgrade My screen normally goes black
when the computer is not in use for some 10 minutes. But it comes back
to life by tapping any key on the keyboard. Stopping at the "change disk"
instruction meant that the computer was doing nothing for 30 minutes or
so. But the keyboard had locked; everything had locked!

Technically, I have subscribed to it and can read the headers of the
daily postings on my news-reader. But queries that I send (via the
newsreader) do not score any reply; they appear (on my newsreader) on the
day that they are sent and vanish without a trace 24 hours later.
The list is monitored and I get a notification every month that I am
still a bona-fide member. Maybe the newsreader-routine is not
acceptable; and I am not prepared to clutter up my mailbox with 150+
emails every day - 98% of them well beyond my comprehension!
Wiping the board clean (reformatting the partition) and starting again is
likely to be less time-consuming than finding and repairing the cause(s)
of a broken dist-upgrade - even if I knew a lot more than I do about
At least I have learned where not to stop and take-a break.
Thank you for the continuing interest and advice.
