答案1

问题：

openssh-server : Depends: openssh-client (= 1:6.6p1-2ubuntu1) but 1:6.6p1-2ubuntu2 is installed.

尝试运行：

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 就可以工作了。

答案2

sudo aptitude install openssh-client=1:6.6p1-2ubuntu1

对我来说效果最好。但是，我没有aptitude安装该命令，因此出现错误：

没有用户‘aptitude’的密码条目

我需要aptitude使用以下命令安装：

sudo apt-get install aptitude

安装完成后，我就可以使用上述命令：

sudo aptitude install openssh-client=1:6.6p1-2ubuntu1

一旦openssh-client=1:6.6p1-2ubuntu1安装了，它是的依赖项openssh-server，我就可以安装ssh。

答案3

版本依赖项不匹配。删除并重新安装以获取正确的版本

apt remove openssh-client
sudo apt-get install opensssh-server

答案4

我已按照@ADITYA SINHA 上述步骤操作...但是，我再次遇到同样的错误。

(base) bandham@BANDHAM:~$ sudo apt-get install aptitude

aptitude is already the newest version (0.8.10-6ubuntu1).
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 uget : Depends: libcurl3 (>= 7.16.2) but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

所以，我必须sudo apt-get install -f修复未满足的错误。它修复了几个类似的包curl,libcurl4,etc。

然后，我只需运行命令sudo apt-get install PACKAGENAME。

快乐学习...
