Comment 1 for bug 2024320

I do see this behavior on Lunar as well:

root@lunar:~# resolvectl query oops.
oops.: resolve call failed: No appropriate name servers or networks for name found
root@lunar:~# dig oops.

; <<>> DiG 9.18.12-1ubuntu1-Ubuntu <<>> oops.

I took a look at the code but I am not sure the best way to address this. Can you please open an upstream bug (https://github.com/systemd/systemd/issues) and share the link here? Be sure to mention that this can be reproduced on v252.
