LanguagePacks
Unlike other distributions we do not ship upstream translations from source packages directly in binary application packages in main and restricted, since this does not allow us any flexibility in editing them on a central place (Launchpad), update them independently from the applications, and update them post release. That is why we separate packages and their translations in Ubuntu and maintain/package them independently.
The complete lifecycle of translations (import, maintenance, export, and language pack structure) is described on TranslationLifecycle.
You can check the latest language packaged (.mo files) from https://launchpad.net/~ubuntu-langpack/+archive.
You can get the source langauge packs (.po files) from Language packs for Jaunty
