With root access I edit the /etc/resolv.conf to add nameserver 8.8.8.8. saving the file give me

"/etc/resolv.conf" E166: Can't open linked file for writing

Do you have a idea? I want to edit resolv.conf because apt-get update is not working.

EDIT I am using 18.04 LTS OS.

  • executing ls -al in /etc shows me: resolv.conf -> ../run/systemd/resolve/stub-resolv.conf. Have you tried editing the linked file (as sudo) directly at /run/systemd/resolve/stub-resolv.conf ?

I reset the system and login graphically. I don't know why but it resolved the problem. I did not edit the resolve.conf anymore.
