I have provided all the necessary steps, which you enter into the terminal.
Are you running a desktop version? That’s unnecessary and not recommended for running Roon Server.
Also, a rolling release such as Fedora is not the best choice if you are new to Linux. You’d be better off using Ubuntu Server 22.04 LTS.
Incidentally, you may have issues running Roon Server on Fedora. I just remembered an issue I encountered with Roon Bridge.
