No. But why should this been done on a YunoHost package level? This is something that should be setup by YunoHost “core”, isn’t it?
The package works in the past and i never change something around the locales. So i think it’s not the problem.
It seems also that this is flaky. But debug flakyness is hard, because CI server are so slow

Yes, sorry about this. That’s the trouble with forum.yunohost.org vs. GitHub. I didn’t quite understand the YunoHost philosophy behind it 
Back to topic: Yes, on Bullseye it works. But it maybe just because of flakiness?!?
