The following bash command adds Medibuntu's repository to Ubuntu. It also adds Medibuntu's GPG key to your keyring, which is needed to authenticate the Medibuntu packages.
This command should be run in the Terminal (Applications → Accessories → Terminal):
sudo -E wget --output-document=/etc/apt/sources.list.d/medibuntu.list http://www.medibuntu.org/sources.list.d/$(lsb_release -cs).list && sudo apt-get --quiet update && sudo apt-get --yes --quiet --allow-unauthenticated install medibuntu-keyring && sudo apt-get --quiet update
Medibuntu's repository is deactivated by upgrading to a newer Ubuntu release, so you should run this command again after the release upgrade.
You may also wish to add the following packages. The first will cause many apps from the Medibuntu repository to appear in Ubuntu Software Center (Ubuntu 9.10+) or Add/Remove Applications (versions prior to 9.10). The second will allow users to generate crash reports against Medibuntu packages and submit them to the Medibuntu bugtracker.
sudo apt-get install app-install-data-medibuntu apport-hooks-medibuntu
The previous command enables access to the main set of Medibuntu servers, located in Europe.
You can choose to use a server nearer from your location. Official mirrors are :
To enable the selected mirror, edit the file /etc/apt/sources.list.d/medibuntu.list and replace http://packages.medibuntu.org with the URL of the server you've selected.
Medibuntu's repository comprises two components: free and non-free.
The free component contains Free software, whose source code is distributed under an open source licence.
Software in the free component is not distributed by Ubuntu because of legal issues with that software in certain countries. Some software –such as mplayer – is distributed by Ubuntu but with certain functionality taken away, again because of legal issues. Medibuntu distributes this kind of software with that functionality in place.
The non-free component contains software whose source code is not distributed under an open source licence. “Non-Free” refers to freedom and not to price.
Software in the non-free component is not distributed by Ubuntu because the software's licence restricts how it can be distributed.
Some people don't want to install Non-Free software on their computer, or simply have no need for the software in Medibuntu's non-free component. The following command deactivates the non-free component.
This command should be run in the Terminal, after adding the repository:
sudo sed -e 's/ non-free//' -i /etc/apt/sources.list.d/medibuntu.list && sudo apt-get update
