I attached shell.log, which indeed shows an error in python; 
unfortunately I don't speak python :-((

I'll do that next.

I don't install recommendations by default, yes (doing so for many
years, albeit this machine is a fairly recent new install).

I know that and I carefully review the list of recommendations each
time I see some.

I have no problem installing additional packages if needed, but I
would expect a programm / environment to at least start up without
recommendations.

Thanks again for your speedy reply.
