We run a public instance of Jira (jira.mariadb.com). Since it's public, it's good to keep it pretty up-to-date so that no known vulnerabilities are open. A couple of weeks back, we started a routine update where we first update the operating system and the libraries available through the repositories configured in the operating system.
The operating system update (apt update and apt upgrade) updated a whole lot of system libraries, but also nginx and MariaDB Server. We use nginx as a reverse proxy in front of Jira. The MariaDB Server update was a minor one; it took MariaDB Server from version 10.3.12 to 10.3.13. At this point, everything worked as normal.
