我无法升级MySQL服务器.这是我试过的：
我首先发出此命令来更新包列表：
sudo apt-get update
然后,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.
显然安装了较新版本(但为什么？我没有手动安装).好的,正如它建议的那样,我发出命令来尝试修复：
sudo apt-get -f install
这是输出：
Reading package lists... Done

Reading state information... Done
Correcting dependencies... Done
The following extra packages will be installed:
mysql-server mysql-server-5.5

然后我尝试使用某些人在互联网上建议的另一个命令：
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
解决方法:
这发生在我身上,但是在做了sudo apt-get更新后,它以某种方式没有得到mysql-server的最新版本,只有mysql-server-core.我首先建议做另一个sudo apt-get更新,然后继续安装包
sudo apt-get install mysql-server
如果这不起作用,那么重新安装：
sudo apt-get install --reinstall mysql-server
如果这不起作用,那么只需清除包mysql-server-core包,然后再次安装mysql-server.
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,重启,安装.
