Bug Description

https://blueprints.launchpad.net/ubuntu/+spec/foundations-o-multiarch-next-steps requires that some clients start downloading Packages files for multiple architectures on 'apt-get update'. As it stands, this will double users' bandwidth costs and time.

We agreed that the correct fix is to move the long descriptions from the Packages files (which are in practice common across architectures) out to the Translation-en file. apt-ftparchive already knows how to do this with a configuration option, and apt-get already knows to fetch the Translation-* files, so all we need is a small change to Launchpad to start doing this for Ubuntu Oneiric and beyond.

https://code.launchpad.net/~cjwatson/launchpad/multiarch-translations has been ready for a while, pending a database deployment which happened today. Jeroen Vermeulen asked me to file this bug to go with it so that it can be used for QA.

OK in the default state (include_long_descriptions = true), but the lucid apt backport seems to hang when attempting to write out Translations.en. Works fine on oneiric, but we should investigate before switching it on in production.

I was able to reproduce the hang and put a fix into lp:~mvo/apt/lucid-apt-ftparchive

I upload a new package with the fix into https://edge.launchpad.net/~mvo/+archive/apt-ftparchive-lucid now.
