If you are experiencing problems (404 errors) with the main mirror, you can find a fallback repository here : http://forum.ubuntu-fr.org/viewtopic.php?pid=554159#p554159

The Penguin Liberation Front is a team that builds litigious packages (packages that are patent encumbered or proprietary). Those packages are meant to be legal and should be used only in countries where software patents don't apply. Please check for the applicable laws in your country !

The PLF repository has been providing litigious packages for Mandriva for many years. Currently the team is doing the same thing for Ubuntu.

If you don't know what a repository means or howto add an extra repository, please read this page !

Packages is this repository can be gpg authenticated. The key that is being used for signing the packages is 12B83718. You can enter this key into the APT trusted keys database with the following command:

wget http://packages.freecontrib.org/ubuntu/plf/12B83718.gpg -O- | sudo apt-key add -

If you also want to add the key to your own keyring, use the following command:

gpg --keyserver hkp://wwwkeys.eu.pgp.net --recv-keys 0x12B83718 ;  gpg --export -a 0x12B83718 | sudo apt-key add -

Then, to use PLF repositories, add the following paragraph to your /etc/apt/sources.list, depending on the Ubuntu release you are using:
