Could you provide a minimalist example?

On my Debian machine, outside the container I get:

--8<---------------cut here---------------start------------->8---
$ LC_ALL=3D"en_US.utf8"
bash: warning: setlocale: LC_ALL: cannot change locale (en_US.utf8)
--8<---------------cut here---------------end--------------->8---

I get that outside the container. It means that you did something
outside you are not doing inside.

I am not convinced by the hack of bug#39665 [1].

I do not know.
