如何重新安裝損壞的mysql包

嘗試修復損壞的 mysql 安裝，這發生在從 debian 6.0 升級到 7.0 之後。我的 /etc/apt/sources.list 中有 dotdeb.org 包。

root@ginger:/var/log/mysql# apt-get install mysql-client

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).

執行 apt-get -f install 結果：

root@ginger:/var/log/mysql# apt-get install -f

知道如何刪除和全新安裝 mysql 嗎？

首先通過以下命令獲取超級使用者權限。 sudo -i會給你root訪問權限。

以下對我有用：

apt-get -f install -o Dpkg::Options::="--force-overwrite"

然後是：

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

對於 MySql5.6 使用以下

apt-get install mysql-client-core-5.6 mysql-client-5.6 mysql-server-5.6

確保備份所有數據，因為這將刪除所有內容。
