请告诉我这里要做什么。 我正在尝试在Ubuntu中安装Hadoop.Ssh连接正在抛出错误

openssh-server : Depends: openssh-client (= 1:6.6p1-2ubuntu1) but 1:6.6p1-2ubuntu2 is installed.
试试跑步：
sudo aptitude install openssh-client=1:6.6p1-2ubuntu1
这将恢复到此版本
然后我这样做了：
sudo apt-get install openssh-server
然后ssh localhost工作。
sudo aptitude install openssh-client=1:6.6p1-2ubuntu1
为我工作最好。 但是，我没有安装aptitude命令并得到错误：
用户’aptitude’没有passwd条目
我需要安装aptitude命令：
sudo apt-get install aptitude
安装完成后，我可以使用上述命令：
sudo aptitude install openssh-client=1:6.6p1-2ubuntu1
一旦openssh-client=1:6.6p1-2ubuntu1安装了openssh-client=1:6.6p1-2ubuntu1 ，这是openssh-server的依赖openssh-server ，我就可以安装ssh 。
