ping通却不能远程连接vmware中ubuntu

在ubuntu终端中输入  ifconfig  命令查询本机ip地址，eht0  (ethernet 因特网的缩写）。
在主机上 ping 此地址是通的，然而用 putty 通过 SSH 连接时却发出 Network Error,connection refused.警告
网上查询发现ubuntu没有ssh服务，[ubuntu开启SSH服务](http://www.cnblogs.com/xiazh/archive/2010/08/13/1798844.html)
照做之后却是
**xxx@ubuntu:~$ sudo apt-get install openssh-server**

[sudo] password for xxx:

The following information may help to resolve the situation:

The following packages have unmet dependencies:

openssh-server : Depends: libck-connector0 (>= 0.2.1) but it is not installable

Recommends: ncurses-term but it is not installable

Recommends: ssh-import-id but it is not installable

E: Unable to correct problems, you have held broken packages.

后来发现是系统没有更新的问题，更行过后再 sudo apt-get install openssh-server

然而用root用户登录不上，最后新建一个用户解决。
