I'm looking at how this works upstream, and in Debian. Upstream: the xpi that can be downloaded from https://addons.thunderbird.net/thunderbird/addon/lightning/ includes all locales. I don't know how this xpi is built though, given that the upstream build system insists on building a localized xpi that contains only one language at a time.
Debian: the extension is unpacked and installed in /usr/share/lightning, and each langpack package installs the corresponding translations in /usr/share/lightning/chrome/lightning/AB_CD/… This works only because the extension is installed unpacked. Note that in Debian there's a separate source tarball for lightning translations (see https://packages.debian.org/source/buster/thunderbird), but maybe that predates the inclusion of lightning in the central repository? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to thunderbird in Ubuntu. https://bugs.launchpad.net/bugs/545778 Title: xul-ext-lightning is only available in English Status in One Hundred Papercuts: Triaged Status in Mozilla Thunderbird: Invalid Status in Ubuntu Translations: Triaged Status in lightning-sunbird package in Ubuntu: Invalid Status in thunderbird package in Ubuntu: Triaged Bug description: ******* ISSUE ******* HOW TO REPRODUCE 1.
