Release-upgrade broke internet connection

[Volker Wysk]

Hi!

The hint, that /etc/resolv.conf should probably point to  
/run/systemd/resolve/resolv.conf was correct. The connection is back.

Now, my desktop (after being online again) sucks all the mail from my  
mail provider, and places it in my local IMAP server (Dovecot). Which  
doesn't work yet. There are problems with kmail. So, at the moment, I  
don't have a working email connection any more. (Last, I've used a  
webmail interface).

I have to repair my mail connection, before I can answer any mail.

Bye, and thanks for that hint!

Volker
