Adding PPA Key BackTrack 5 R1

Open terminal(whatever console program). For example, i use gnome-terminal.. Simply login as "root". Yupps, only root access allowed to do this action. You can proceed by typing "sudo -i" then enter password for root.

Format is:
[sudo add-apt-repository] [PPA KEY]

For example i want to add PPA Key for wine. Here it should become like this:
"sudo add-apt-repository ppa:ubuntu-wine/ppa"
