I just ran the install script on debian 12 as I'm rebuilding our server. I let it install mysql via the script and it died out as mysql was unable to start.
I had to manually install the following packages: mariadb-plugin-provider-bzip2 mariadb-plugin-provider-lz4 \ mariadb-plugin-provider-lzma mariadb-plugin-provider-lzo \ mariadb-plugin-provider-snappy
The errors showing these were missing:
mariadbd[1605]: 2025-06-08 5:48:20 0 [ERROR] /usr/sbin/mariadbd: unknown variable 'provider_bzip2=force_plus_permanent' mariadbd[1605]: 2025-06-08 5:48:20 0 [ERROR] /usr/sbin/mariadbd: unknown variable 'provider_lz4=force_plus_permanent' mariadbd[1605]: 2025-06-08 5:48:20 0 [ERROR] /usr/sbin/mariadbd: unknown variable 'provider_lzma=force_plus_permanent' mariadbd[1605]: 2025-06-08 5:48:20 0 [ERROR] /usr/sbin/mariadbd: unknown variable 'provider_lzo=force_plus_permanent' mariadbd[1605]: 2025-06-08 5:48:20 0 [ERROR] /usr/sbin/mariadbd: unknown variable 'provider_snappy=force_plus_permanent' mariadbd[1605]: 2025-06-08 5:48:20 0 [ERROR] Aborting systemd[1]: mariadb.service: Main process exited, code=exited, status=7/NOTRUNNING
Once I did this, it came up and works.
