I'm a brand new Fedora user, but have used Ubuntu for a while and they seem pretty similar.
I'm having a problem trying to install an .rpm file, as I get the authorization message , type in my password (the one I use when I log on) and it says 'authentication failure'.
I'm also unable to overcome this by using a terminal to install, as I can't become super user when it rejects my password.
I've changed my password using the 'passwd' command and it changes my login password but still does not let me authorize any system changes/installs etc.
As I say, I'm brand new to Fedora, any help would be greatly appreciated.
