[Solved] Missing /etc/systemd/resolved.conf file (lemmy.dbzer0.com)

Solution: I just had to create the file

I wanted to install Pi-Hole on my server and noticed that port 53 is already in use by something.

Apparently it is in use by systemd-resolved:

~$ sudo lsof -i -P -n | grep LISTEN
[...]
systemd-r    799 systemd-resolve   18u  IPv4   7018      0t0  TCP 127.0.0.53:53 (LISTEN)
systemd-r    799 systemd-resolve   20u  IPv4   7020      0t0  TCP 127.0.0.54:53 (LISTEN)
[...]

And the solution should be to edit /etc/systemd/resolved.conf by changing #DNSStubListener=yes to DNSStubListener=no according to this post I found. But the /etc/systemd/resolved.conf doesn't exist on my server.

I've tried sudo dnf install /etc/systemd/resolved.conf which did nothing other than telling me that systemd-resolved is already installed of course. Rebooting also didn't work. I don't know what else I could try.

I'm running Fedora Server.

Is there another way to stop systemd-resolved from listening on port 53? If not how do I fix my missing .conf file?

Yep, it might be enough to just add that file with the setting set to no and restart.
