As a consequence, you might see error messages in the Update Manager, Package Manager and Software Manager.
The solution is to remove Medibuntu from your list of repositories:
- Open a terminal
- Type gksu gedit /etc/apt/sources.list to edit the list of repositories (replace “gedit” with “pluma” if you are running MATE, or with “kate” if you are running KDE)
- Remove any line which contains “medibuntu” in it and save the file
- Type apt update in the terminal
- If you are running Linux Mint 15 you’ve nothing to do (Medibuntu isn’t used in Mint 15)
- If you are running the KDE edition, sources might not be present in /etc/apt/sources.list but in another file in the /etc/apt/sources.list.d/ directory instead
In Linux Mint 16 onwards libdvdcss2 (which allows us to watch DVDs) will be provided via a new Linux Mint repository at http://extra.linuxmint.com.
