[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?

The service is using the default config, which you can override by creating this file.

View the package contents to find out where the default config is located.

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