试图修复损坏的 mysql 安装，这是在从 debian 6.0 升级到 7.0 之后发生的。我的 /etc/apt/sources.list 中有 dotdeb.org 包。

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
mysql-server-5.5 : Depends: mysql-client-5.5 (>= 5.5.31+dfsg-0+wheezy1) but 5.5.30-1~dotdeb.0 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
运行 apt-get -f install 结果：
root@ginger:/var/log/mysql# apt-get install -f

知道如何删除并全新安装 mysql 吗？
首先通过以下命令获取超级用户权限。
sudo -i会给你root访问权限。
以下对我有用：
apt-get -f install -o Dpkg::Options::="--force-overwrite"
然后是：
apt-get purge mysql\*
rm -rf /var/lib/mysql
rm -rf /etc/mysql
dpkg -l | grep -i mysql
apt-get clean
updatedb
apt-get install mysql-client-core-5.5 mysql-client-5.5 mysql-common mysql-server-5.5
对于 MySql5.6 使用以下
apt-get install mysql-client-core-5.6 mysql-client-5.6 mysql-server-5.6
确保备份所有数据，因为这将删除所有内容。
