mailman3-web 0+20180916-10 (amd64 binary) in ubuntu focal

 This django web application provides the Mailman3 Postorius web interface
 and the HyperKitty mailinglist archiver integrated into one project.
 .
 The package automates most of the necessary configuration for the Django
 project (database setup, webserver configuration, secret and API key
 generation, Django project configuration) to get a ready-to-use Mailman3
 web suite.
 .
 The Mailman3 Django project runs as uWSGI daemon and optionally a webserver
 is configured as reverse proxy. In this case, the service can be accessed
 at '/mailman3'.
 .
 Default database backend is SQLite3 in order to not break automated
 installations. For productive setups, PostgreSQL or MySQL are much better
 options though. See README.Debian for further information.
