错误命令行

root@ubuntu:/etc/apt# apt install vim
Reading package lists... 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:
 vim : Depends: vim-common (= 2:7.4.052-1ubuntu3.1) but 2:8.0.1453-1ubuntu1 is to be installed
E: Unable to correct problems, you have held broken packages.

原因

已有安装过vim，但没有安装成功

解决方案

1. 先执行 sudo apt-get remove vim-common  卸载vim-common
2. 再进行安装vim，执  sudo apt-get install vim 

举一反三

执行安装命令的时候，只要报出类似这样的错误，则需要先remove，然后再次install；下面这个就是 apt-get install openssh-client 报的错误，解决方案相同

重点在于： Unable to correct problems, you have held broken packages. ，表示有一个破碎的包

The following packages have unmet dependencies:
 openssh-server : Depends: openssh-client (= 1:6.6p1-2ubuntu2.13)
                  Recommends: ssh-import-id but it is not going to be installed
