I think your MariaDB is too old.
The minimum supported MariaDB is 10.2.2.

From:

21.3.0 Release

LibreNMS version 21.3.0 has been released! We thank each and every of the 27 different contributors to LibreNMS this month. Make sure you thank them for their time and effort If you would like help with LibreNMS in any way, let us know in Discord. The minimum supported MySQL / MariaDB version is now 5.7.7 / 10.2.2 Please make sure you upgrade sooner than later. Notable changes: PHP 8 support! (We still recommend PHP 7.4 for time being being tho) 15 devices have new or update…
