my Apache2 on Ubuntu 16.04 runs mpm_event, but on every Security Update Apache switch back to mpm_prefork. Why and how can I disable this, so mpm_event is still configured?
I found this: https://ubuntu101.co.za/apache-web-server/fix-apache-2-4-loading-wrong-mpm-worker-module/
But this don't work for me. After a security update I get the error message: "No MPM is configured". So my Apache don't run.
Did you have an idea?
