Playbook fails on "ensure mariadb-server is enabled and started" step about ansible-nextcloud HOT 2 CLOSED

Confirmed here. Option was not in my file, as it is added only when: mariadb_installation.changed, but if I add the option manually, mariadb does not start and complains about this option:

from ansible-nextcloud.

The problem was that this option was introduced in mysql version 5.6. As we are using custom mirrors, we got more recent mysql versions so we did not see this issue. Should be fixed now.
