Hi, As you can see, the error message seems quite clear: > Cannot update applied migration 'authentication.0001_initial'. One cannot edit a migration that has already been applied. To update it, you can undo it by running "migrate authentication zero" and then run "makemigrations --update" again.
I do not think it's a bug in Django.
