User creation fails due to missing`mailman` group

Comienza reproduciendo el fallo en gnumailman.nyc1.psf.io e inspecciona la configuración que define el grupo mailman y los usuarios afectados. Rastrea por qué los requisites de user.present no pueden encontrar group: mailman y, a continuación, verifica que los usuarios y sus estados dependientes de directorio SSH y claves se completen correctamente.

The following error happens now on gnumailman but further inspection will show that:

1. this group exists already
2. these users exist already
3. these users are IN the group...
