Just for kicks, I decided to play a bit with Fedora 23 beta. Yes, I know it's not supposed to work like a production distro, but I thought it would be fun to poke around on it a little. I sorta need to install a couple of packages from rpmfusion, though. Unfortunately, they don't have a Fedora 23 setup out yet.
I tried to install the Fedora 22 repositories, but it didn't work.
I get the error:
Failed to synchronize cache for repo 'rpmfusion-free' from 'http://mirrors.rpmfusion.org/mirrorlist?repo=free-fedora-23&arch=x86_64':
Cannot prepare internal mirrorlist: No URLs in mirrorlist, disabling.
So, how would I go about, say, installing mplayer in Fedora 23 beta?
