I'm pretty sure I followed this guide when I installed MariaDB on Hera 5.1.7 a few weeks ago, and MariaDB 10.1 was installed. This week, I needed to update MariaDB so I ran mysql_upgrade, which told me I was already upgraded to "10.1.48-MariaDB." Trying apt-cache policy mariadb-server, apt reports only 10.1.48 as the available candidate... I even tried removing and re-installing MariaDB and still got 10.1. So I'm guessing that as I was following random online guides when building the LAMP server, I installed a repository that specified 10.1 as the MariaDB to use and now, my machine is unware of any newer versions. I've tried looking at the sources lists and don't see anything specific to MariaDB. Any idea what could be the problem? elementary OS 5.1.7 Hera (GNU/Linux 5.4.0-42-generic x86_64) Built on Ubuntu 18.04.4 LTS Code (Text): ~$ sudo apt-cache policy mariadb-server; mariadb-server:
