I'm trying to create a list (on Ubuntu) and I'm getting this:

<venv> $ python3
Python 3.12.3 (main, Aug 14 2025, 17:47:21) [GCC 13.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> owners = ['[email protected]']
>>> from mailman.app.lifecycle import create_list
>>> ant = create_list('[email protected]', owners)
Traceback (most recent call last):
