Resolution: Won't Fix
During the recent AMOS upgrade (
MDLSITE-6243) the scripts making snapshots of language packs contents into the git://git.moodle.org/moodle-langpacks.git (https://git.in.moodle.com/moodle/moodle-langpacks.git) were removed.
It turns out there were sites relying on this secondary channel of language packs distribution.
We should make it work again.
