Medibuntu is going down.
To disable the Medibuntu repository and enable the libdvdcss one, use these commands:
sudo rm /etc/apt/sources.list.d/medibuntu.list curl ftp://ftp.videolan.org/pub/debian/videolan-apt.asc | sudo apt-key add - echo "deb ftp://ftp.videolan.org/pub/debian/stable ./" | sudo tee /etc/apt/sources.list.d/libdvdcss.list sudo apt-get update
If you are using Ubuntu saucy, you can also install libdvdcss using an alternative method (make sure to install/upgrade the libdvdread4 package first).
I'll keep the repository online for now, at least until the Ubuntu 13.10 release. Expect the repository to be down after that. An iso image of the current state of the repository is available <http://archive.pocentek.net/medibuntu/>.
I recommend to disable the repository if you are currently using it.
Thanks to all the persons who contributed to the project (package maintainers, servers admins, ...).
