Ok I found how to recover these snap-native langpacks. Config editor, search "lang" and reset the adequate values, see attachment.
If I do that, the version is up-to-date and I still get "Inbox" not translated at first launch after langpack activation. Maybe a TB related bug, not snap. Are Groovy TB 78 users seeing the same issue? ** Attachment added: "Capture d’écran de 2020-10-29 11-12-48.png" https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/1899025/+attachment/5428939/+files/Capture%20d%E2%80%99%C3%A9cran%20de%202020-10-29%2011-12-48.png -- 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/1899025 Title: snap translations issue during 1st launch after update Status in thunderbird package in Ubuntu: New Bug description: When I updated today from 78.3.1 to 78.3.2, after the first launch of the updated 78.3.2, I got some untranslated strings (Inbox in mailboxes folder list, e.g.). After the 2nd launch, all became normal. AFAICR, it was the case during previous updates too. Not a big deal, though...
