云服务器 ECS Ubuntu 安装 MySQL Server 提示 mysql-server :
使用 Ubuntu 14.04 系统在安装 mysql-server 时出现如下报错信息：
eading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
mysql-server : Depends: mysql-server-5.5 but it is not going to be instaed
E: Unable to correct problems, you have held broken packages.
可以看到报错是无法解决 mysql-server 安装时的依赖关系导致的。
因为用户是使用 apt-get 的方式安装的，那么这种安装方式通常是能够自动解决依赖关系。

问题原因
因为系统自带的安装源无法解决安装包依赖问题，更换为新的安装源，解决包依赖问题，安装软件。
解决方案
- 方案一：修改系统 apt-get 更新配置文件
- 方案二：下载阿里云官方 apt-get 源更新脚本
方案一
cp -a /etc/apt/source.list /etc/apt/source.list.bak //备份/etc/apt/source.list文件 vim /etc/apt/source.list在最前面添加一下内容
