解决办法如下：

尝试使用以下命令

sudo apt-get install -f

来查看它是否能修复破坏的依赖项.

如果失败,清除MySQL服务器：

 sudo apt-get purge mysql-community-server mysql-community-server 

然后清理并更新：

 sudo apt-get autoclean && sudo apt-get clean && sudo apt-get update 

做一般升级：

 sudo apt-get upgrade 

现在尝试重新安装：

sudo apt-get install mysql-server and mysql-community-server 

如果从root提示符执行此操作,则不会引导前导sudo命令.
