各位好，我在自己的 Ubuntu 20.04 机器上碰到了 MariaDB 启动失败的问题，折腾好一阵子都没搞定，先给大家贴一下我的系统和已安装的 MariaDB 版本信息：

root@riccardo-Inspiron-15-3520:/home/riccardo# uname -a
Linux riccardo-Inspiron-15-3520 5.15.0-122-generic #132~20.04.1-Ubuntu SMP Fri Aug 30 15:50:07 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux
root@riccardo-Inspiron-15-3520:/home/riccardo# lsb_release -crid
Distributor ID: Ubuntu

ii mariadb-server-10.3 1:10.3.39-0ubuntu0.20.04.2 amd64 MariaDB database server binaries

我尝试用 systemctl start mariadb 启动服务时直接失败了，查看服务状态显示处于失败状态，也看过 /var/log/mysql/error.log 里的日志，但没找到明确的错误指向。有没有大佬能给我一些排查思路，或者帮我分析下可能的问题原因？感谢各位！
