Y PPA Manager is available for Ubuntu 9.10, 10.04, 10.10 and 11.04 – install it using the commands below:
sudo add-apt-repository ppa:webupd8team/y-ppa-manager
sudo apt-get update
sudo apt-get install y-ppa-manager
Tip: I recommend installing the patched NotifyOSD package from Leolik’s PPA – that will allow Y PPA Manager to specify the time to display the notification bubbles so they will dissapear depending on importance and not always after 10 seconds (that’s how the default NotifyOSD in Ubuntu works).
