Following the docker documentaiton for installing docker and docker-compose, and the mailcow documentation for installing mailcow-dockerized: I get an error when running docker-compose up -d. At the end I get an error at Creating mailcowdockerized_postfix-mailcow_1. Running docker-compose ps shows everything up save postfix, which reports mailcowdockerized_postfix-mailcow_1 /docker-entrypoint.sh /bin ... Exit 128.
EDIT: This is on a perfectly clean VPS running Debian 10.
