Thanks for your speedy reply. However I disagree with your diagnosis.
The problem I reported seems to have been fixed by a series of updates,
that I downloaded shortly after sending you the log. So a software patch
seems to have made the problem vanish,
Whatever problems my harddisk has did not have ANY impact on browsing
files in 18.04. As I reported initially, the problem started ONLY and
IMMEDIATELY after the initial 20.04 upgrade.
I therefore looked at the immediate PRECIPITATING CAUSE of the problem,
version upgrade, before assuming it is a hardware problem.
Anyway, thanks again for your time.
