All right, the problem seems to be that you don't have the linux- restricted-modules package for your kernel installed.
Restricted-manager probably should depend on such package – perhaps each linux-restricted-modules-* package could provide "linux-restricted- modules", on which r-m could depend on. Or alternatively it could complain about the missing package. For now, you should be able to fix the problem by running sudo apt-get install linux -- ATI 9600 onboard: restricted-manager says "your hardware does not need any restricted drivers" https://launchpad.net/bugs/95145 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
