I literary just installed fedora for the first time and the nvidia drivers a few minutes ago. I thought the method for adding repositories was the same as ubuntu, so I tried to add a ppa, and now I'm getting an error every time I enter any command.
Repository 'numix_ppa': Error parsing config: Error parsing "baseurl = 'ppa:numix/ppa'": URL must be http, ftp, file or https not "ppa"
