Comment 8 for bug 1161743

@vofka: Good catch. I played with an equivalent file on groovy for Swedish, and it looks like apt (apt-cache) only looks for groovy-updates_*_i18n files while ignoring the groovy_*_i18n ones. And no localized groovy-updates_*_i18n files are present; only English files are:

/var/lib/apt/lists$ ls -1 *ubuntu_dists_groovy-updates_*_i18n*
archive.ubuntu.com_ubuntu_dists_groovy-updates_main_i18n_Translation-en
archive.ubuntu.com_ubuntu_dists_groovy-updates_multiverse_i18n_Translation-en
archive.ubuntu.com_ubuntu_dists_groovy-updates_restricted_i18n_Translation-en
archive.ubuntu.com_ubuntu_dists_groovy-updates_universe_i18n_Translation-en

I don't know how this is supposed to work exactly.

@Sebastien: Can you shed some light on it?
