Ubuntu 16.04 安装完vSphere虚拟机之后，如果想装ssh软件进行连接，发现几乎所有的包都装不成功。

root@zengxijin-va:/home/zengxijin# apt-get install openssh-server

Package openssh-server is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package ‘openssh-server’ has no installation candidate

报的报错都是Package ‘xxx’ has no installation candidate。
解决办法：
（1）备份/etc/apt/sources.list

  1. sudo cp -i /etc/apt/sources.list /etc/apt/sources.list.backup

（2）更新repos
将以下的内容添加到/etc/apt/sources.list（或者将原来的内容清空再添加下面的源）

  1. deb http://archive.ubuntu.com/ubuntu/ trusty main restricted universe multiverse 
  2. deb http://archive.ubuntu.com/ubuntu/ trusty-security main restricted universe multiverse 
  3. deb http://archive.ubuntu.com/ubuntu/ trusty-updates main restricted universe multiverse 
  4. deb http://archive.ubuntu.com/ubuntu/ trusty-proposed main restricted universe multiverse 
  5. deb http://archive.ubuntu.com/ubuntu/ trusty-backports main restricted universe multiverse

然后更新：

  1. sudo apt-get update

再执行

  1. sudo apt-get install openssh-server

然后就能安装成功了，如果遇到版本依赖的冲突，先按照提示安装对应的依赖版本：如

  1. apt install openssh-client=1:6.6p1-2ubuntu2.10

再正常安装对应的软件包就可以了哈。
