Install Kubuntu. The following 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.

wget --output-document=/etc/apt/sources.list.d/medibuntu.list http://www.medibuntu.org/sources.list.d/$(lsb_release -cs).list
apt-get --quiet update
apt-get --yes --quiet --allow-unauthenticated install medibuntu-keyring
apt-get --quiet update

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.

apt-get --yes install app-install-data-medibuntu apport-hooks-medibuntu
