我升级到了 12.04，我的 MySQL 服务器停止工作了。它抛出：
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
我尝试从软件中心重新安装它，但失败了：
Package operation failed
The installation or removal of a software package failed.

Virtual packages like 'mysql-server-5.1' can't be removed
The following packages will be REMOVED:

你可以尝试：
sudo apt-get -f install
