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). Regards, Steffen
