Hi everyone, so I’m having this weird issue. No matter the DNS and IP settings I use in NetworkManager, it will always generate the same resolv.conf.

resolv.conf

# Generated by NetworkManager
nameserver ::1

IPv6 is disabled by the way.

    is /etc/resolv.conf a symlink?

      I actually thought about that too, but it isn’t.

      #: file /etc/resolv.conf
/etc/resolv.conf: ASCII text

    I’m not sure but this might have to do with systemd-resolved. You may want to disable it, that might fix your problem

      Thought about that too, but I don’t have resolvd nor systemd-resolv or systemd-resolve active. Nor do I have avahi running. Interesting isn’t it?

        Do you have any DNS server on port 53? If so, could you check which process or application it is?

          Nope :( Neither dnsmasq nor bind are installed. Nothing on port 53 either.

    I just found this file, now sure if it’s related or not.

    $: cat /run/NetworkManager/resolv.conf
# Generated by NetworkManager
nameserver ::1

    and

    $: cat /run/NetworkManager/no-stub-resolv.conf
# Generated by NetworkManager
nameserver ::1

    Edit: those are generated from the /etc/resolv.conf NM generates.

    Move to ----> systemd-networkd 😉 . Btw check your system isn’t also running something systemd-resolved that you probably will want to disable as you are using NM.

      I don’t have systemd-resolved installed.
