升级 MySQL 服务器问题

Question

我升级 MySQL 服务器失败。这是我尝试过的：

我首先发出这个命令来更新包列表：

sudo apt-get update

然后，通过以下方式升级：

sudo apt-get upgrade

它显示以下错误：

Reading package lists... Done
Building dependency tree       
Reading state information... Done
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 mysql-server-5.5 : Depends: mysql-server-core-5.5 (= 5.5.28-0ubuntu0.12.04.2) but 5.5.31-0ubuntu0.12.04.1 is installed
E: Unmet dependencies. Try using -f.

显然安装了更新的版本（但为什么？我没有手动安装）。好的，正如它所暗示的，我发出命令来尝试修复：

sudo apt-get -f install

这是输出：

然后我尝试使用网上有人建议的另一个命令：

sudo apt-get -f upgrade

产生相同的输出。除了重新安装 MySQL 服务器，我还能做什么？

使用 Ubuntu 服务器 12.04 LTS

那发生在我身上，但它是，在做了sudo apt-get update之后不知何故没有得到最新版本mysql-server的mysql-server-core. 我会首先建议做另一个sudo apt-get update然后继续安装包

sudo apt-get install mysql-server

如果这不起作用，请重新安装：

sudo apt-get install --reinstall mysql-server

如果还是不行，后来干脆purge包mysql-server-core封装，然后再安装mysql-server一次。

sudo apt-get purge mysql-server-core mysql-server-core-5.5

sudo apt-get install mysql-server

如果这不起作用，那么就疯狂吧：

sudo apt-get clean

sudo apt-get autoclean

sudo apt-get purge mysql-server*

sudo apt-get install mysql-server

作为最后的手段，我会清除、重新启动、安装。
