Public bug reported:
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
