With my up to date Nextcloud setup I’m currently using MariaDB 10.5.17-alpine, last updated 27 Sep 2022, as shown here: https ://fleet.linuxserver.io/image?name=linuxserver/mariadb.
It appears the alpine flavour of MariaDB is not updated often. Is it a concern? Should I switch to the latest 10.11.5? Is that even easy?
