[debian-mysql] Bug#1001843: libmariadb-dev: mariadb_config reports incorrect plugin directory

[Akira Miyakoda]

Package: libmariadb-dev
Version: 1:10.5.12-1+b1
Severity: normal
X-Debbugs-Cc: akira.miyakoda at gmail.com

Dear Maintainer,

Since Debian 11 or Ubuntu 21.10, the command 'mariadb_config --plugin' returns '/usr/lib/arm-linux-gnueabihf/libmariadb3/plugin' which doesn't work. MariaDB server doesn't load the plugins installed in the directory. I
think it should be '/usr/lib/mysql/plugin/'.
The same issue occurs on x86_64 systems too.

It returned the correct directory on Debian 10 or Ubuntu 20.04 as far as I tried.

Thanks, Akira.
