apt-get install mysql-server 不询问 root 密码并且服务器无法启动

我之前已在 Ubuntu 16.04 上成功安装mysql-server，但由于我不记得 root 密码并且没有创建数据库，因此我尝试重新安装它。我尝试了很多次，但似乎该过程没有完成，因为它没有要求输入 root 密码，也没有在/etc和中创建 mysql 目录/var/lib。因此，服务器无法启动。

这是我删除 mysql-server 的方法：

sudo apt-get remove --purge mysql-server 
sudo apt-get autoremove
sudo apt-get autoclean
sudo rm -rf /var/lib/mysql* /etc/mysql*
deluser mysql
delgroup mysql

重新安装日志：

我最终重新安装了 Ubuntu。我想这个解决方案可能不适用于其他情况，但这就是我所做的。
