Thank you for your help! Yes, good idea!
  (I don't have it, but a good point. Related, I
  read often in internet of similar possible issues with
  some network manager versions)

I couldn't see the cause in the whole file system, and as
Thankfully Pierre-Elliott Bécue correctly saw from a wide
distance that this is because - it is in fact not in the
file system. But outside. Namely a virtualisation
environment set it into a container (the machine
actually is "just" a container).
