The official software repositories from Ubuntu, as opposed to PPAs and 3rd-party repositories

This tag is for questions relating to the official Canonical-managed software repositories that come with Ubuntu. These include the release, release-security, release-updates, and release-proposed repositories (including the sections /main, /restricted, /universe, and multiverse). Official repositories are distinguished from s (repositories hosted on Canonical's Launchpad infrastructure but managed by individuals or groups) and from third-party repositories (e.g. Medibuntu).
