Btw, in my case, I just uncomment the following line in config.yml :

framework:
    translator: { fallbacks: ['%locale%'] }

And my locale was set to "fr"

parameters:
    locale: fr

Symfony 4.4/5/6+

Change fr by the locale you want to make default:

# config/packages/translation.yaml
framework:
    default_locale: fr
