When i try to type any sudo command i get an error: "sudo: unable to cache user root, already exists"
I have tried to repair premissions but still same error.
MacBook Air, OS X Mountain Lion (10.8.4)
Is your user account an "Admin" account?
Back up all data, then reinstall the OS. You don't need to erase the startup volume, and you won't need your backup unless something goes wrong. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it.
I first tried to repair premission errors but that didnt work, so i rebooted and pressed cmd + R and tried to rapair in diskutility from there, but no success..
I then reinstalled the OS by rebooting and pressing cmd+R. This process took about 1 hour and now it works!
