Hi,
I'm trying to install Mailman 3 on Debian 9. However, it doesn't let me do. ... KeyError: 'env_py'
This is the issue reported at <https://gitlab.com/mailman/mailman/issues/423>. It is caused by a change in Alembic 0.9.6. If you downgrade Alembic to 0.9.5, it will work, or you can install the fix at <https://gitlab.com/mailman/mailman/commit/24f2439aeabb5919d387d84aa9f66b5d79...>
