[Samba] samba-tool gpo listall error

[Jonathan Kreider]

More problems...

So cat /etc/resolv.conf yields nothing.
root at ad2:~# ll /etc/resolv.conf
lrwxrwxrwx 1 root root 39 Jun 17  2018 /etc/resolv.conf ->
../run/systemd/resolve/stub-resolv.conf

Shows a broken link. Since this is Ubuntu 18.04 with systemd and the
stub-resolv.conf missing, I'm lost. I'll test my google fu to try to figure
this out, but if someone can point me in the right direction, I'd be most
grateful.

I presume that the python code gets its info from /etc/resolv.conf rather
than a DNS query? (Since ping works...)

Thanks,
Jonathan Kreider
