To install Playdeb, you can:
1. Download and install updated apturl package.
* install the playdeb package (if you'll get a dialog asking you for confirmation, press Y)
* or add this line to System-Administration-Software Sources, Third-Party Software tab:
deb mirror://www.getdeb.net/playdeb-mirror/hardy/// hardy/
(three trailing slashes are intentional)
Once this is done. To install any game now only have to go to Add and Remove and set up ... "All available applications." Now we can install any application with two clicks.
See the available games section for those!
