Your problem with nvidia drivers and I quote
The reason of my post was a package from nvidia which replaced partially 390xx drivers without possibility to stop that
This is due to the fact you used
apt upgradeLet this be a lesson to you
If you want to carry on with the way you are using apt, at least do
apt update; apt upgrade -s
and you have to compare that with
apt update; apt full-upgrade -s
or
apt upgrade --install-new-pkgs -s
melmarker beat me on this one
Humans are sometimes illogical
Live long and prosper
