[MM3-users] Mailman3 virtualenv installation: missing data

Hi all,

i tried to install Mailman3 according to https://docs.mailman3.org/en/latest/install/virtualenv.html#virtualenv-insta.... I’m using Mariadb instead of PostgreSQL, but that is no problem until now. Where i fail: I have to make an entry var_dir: /opt/mailman/mm/var in /etc/mailman3/mailman.cfg. But there is no directory /opt/mailman/mm, and there are no subdirectories. No $var_dir, no postfix_lmtp, no postfix_transports. Where do i get those files from?

TIA QNo
