Fedora 22 has depreciated Yum.
They now use dnf
Fedora 22 is going to be released in something like 13 days… We’re going to get lots of questions about this.
I was going to attempt a FOG install on the Fedora 22 server Beta, but ran into the dnf stuff and just turned the other way because I’m in a rush.
If the syntax is similar to yum, we could make a temporary alias to change out yum to dnf. I don’t imagine the installation of packages would change too much.
