Title:
  resolv.conf symlink is broken

Status in systemd package in Ubuntu:
  Confirmed

Bug description:
  see description here: https://askubuntu.com/a/1041631/436647

  *The Default*

  $ ls -l /etc/resolv.conf

  lrwxrwxrwx 1 root root 39 Apr 26 12:07 /etc/resolv.conf ->
  ../run/systemd/resolve/stub-resolv.conf

  I deleted this and pointed to the correct file. After rebooting, this
  solved my issue. And I was even able to switch networks on my laptop
  and the DNS switched correctly. Of course when on external networks I
  can't resolve any of my local machines but that is expected. As soon
  as I switch back to my local network, all the local machines resolve
  correctly because my router is the DNS.

  -------------------------------------
  *The Fix*

  $ sudo rm -f /etc/resolv.conf
  $ sudo ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf
  $ ls -l /etc/resolv.conf

  lrwxrwxrwx 1 root root 32 May 29 08:48 /etc/resolv.conf ->
  /run/systemd/resolve/resolv.conf

  $ sudo reboot
