Can anyone help please, I know what my problem is now but dont know how to fix it.

I checked the repositories and they had no distribution listed, I made it diablo and now I have to updates available:

Operating system and makedev (2.3.1-73osso-4)

Both say they are uninstallable because the other is missing, when I try to install them they say "go ahead anyway", I say yes but it fails.

As they are reliant on each other how can I fix this?
