Testweise habe ich apparmor mal ausgeschalten, dennoch wird mariadb nicht gestartet. ich hatte auch versucht die Datei /etc/apparmor.d/local/usr.sbin.mysqld zu nach nach diesem Beitrag https://askubuntu.com/questions/916009/mysql-wont-start-because-of-apparmor zu editieren. Doch das hatte keinen Effekt. Das Thema ist doch nichts neues. Was muss ich machen, damit mariadb startet?
