Skype will no longer be present in the Medibuntu repository.

For several years, Skype in Ubuntu and its relatives could be installed in the traditional way, using the repository and two clicks.

This repository was Medibuntu , containing “entertaining” software and codecs that were not included in the main repositories for licensing and patent reasons.

And on December 9, Lionel Le Folgoc, a developer from the Ubuntu Core Development Team and one of the Medibuntu managers, announced the removal of Skype from Medibuntu. Here is how it is explained :

It is somewhat problematic to support our Skype packages (skype, skype-common, skype-static and skype-static-oss), since [our] skype-common conflicts with packages on skype.com and it's not easy to avoid it (unless you re-enable skype- common in skype and skype-static, which in itself is not easy). After some discussion on irc with the developers of Skype, I believe that the best solution would be to stop providing these packages. Skype will undoubtedly upload i386, amd64 and skype-static packages to skype.com.

At the moment the packages will be moved to the * -staging repository, and after they are published on skype.com, we will remove them completely.

Thus, those who want to install Skype are now recommended to download it directly from the site . Which, of course, is a bit sad, because you can at least forget about the standard package update mechanism.
