I tried running that command, and got more outupt than I could go back
to the first lines of the output to see what was there, so, because
you mentioned the prospect of unattendedf updates ()which are supposed
to be disabled on this computer, I loaded Software Updater, and the
first screen that I saw, showed that it was installin packages. It did
not let me stop what it was doing, so I had to sever the Internet
connection, to stop it making unauthorised downloads.

Then, the screen started flashing (?) black screens.

I have no idea how the system updater has gone dirty, but, it appears
safest to disable the system updates, as the software appears to have
gone rabid, maliciously taking control of the system.

So, I will reconnect to the Internet, send this message, and,
disconnect again, and, try to reconnect from time to time, to seek an
answer to this - I mayu have to use another computer to connect to the
Internet, to try to find a solution, as the operating system appears
to have made it toodangerous to connect this computer to the Internet.
