我尝试重新安装 MariaDB，我使用了：
sudo apt-get purge mysql* mariadb*
但是，上述尝试失败后，唯一剩余需要卸载的软件包是mariadb-server-10.0。
当我尝试使用以下命令清除它时：
sudo apt-get purge mariadb-server-10.0
我得到了这个输出：
Reading package lists... Done

The following packages were automatically installed and are no longer required:
libdbi-perl libterm-readkey-perl
Use 'apt-get autoremove' to remove them.
The following packages will be REMOVED:

MariaDB 是 MySQL 的一个开源版本（没有母公司 Oracle 的任何麻烦）。您需要从 MariaDB 的安装日志中找出 MySQL 的安装位置（它可能位于 /etc/init.d 下），然后停止它
sudo /etc/init.d/mysql stop
完成后，执行您要执行的相同操作。
