Can not import countries or currencies


I’m trying to import currencies and countries into a new database. I installed account module and dependencies. The command is:

trytond_import_countries -c tr.conf -d mydb

The error message is:

trytond.model.modelstorage.SelectionValidationError: The value "en_US" for field "Language" in ",name" of "Translation" is not one of the allowed options. -

I already installer English language. I’m using trytond==6.6.3. Same command works on 6.0, 6.2 and 6.4.

I guess the language of the admin user is not valid.

Effectively that is. I need to set admin user language.

PD. May be useful to add the en language as default.
