Comment 11 for bug 761723

The procedure at the link I posted in comment #9 is meant to be used on Natty. I'm not even sure if you can add the natty-proposed repositories to Maverick. Alternatively, you can open Synaptic Package Manager (on Natty), choose Repositories from the Settings menu and then select the Updates tab and then select Pre-released updates (natty-proposed), reload the package information, then use the quick search box to search for linux.
