一定要先对源进行升级。

sudo apt-get update

我这里出错

W:Failed to fetch http://repo.MysqL.com/apt/ubuntu/dists/trusty/InRelease

升级失败后面的安装就不会成功。

官网查询后：

shell> sudo apt-get update
W: Failed to fetch http://repo.MysqL.com/apt/ubuntu/dists/trusty/InRelease
Unable to find expected entry 'utilities-1.4/binary-amd64/Packages' in
Release file (Wrong sources.list entry or malformed file)

在升级就ok.

执行：
apt-get install MysqL-server

报错：

E: The package MysqL-community-server needs to be reinstalled,but I can't find an archive for it.
