apt-get依赖项问题Open-SSH客户端
这是在Ubuntu 12.04服务器上。
我在尝试运行任何apt-get install时遇到此错误（尝试安装不相关的任意软件包）：
dpkg: dependency problems prevent configuration of openssh-server: openssh-server depends on openssh-client (= 1:5.9p1-5ubuntu1.1); however: Version of openssh-client on system is 1:5.9p1-5ubuntu1.4. dpkg: error processing openssh-server (--configure): dependency problems - leaving unconfigured No apport report written because the error message indicates its a followup error from a previous failure. dpkg: dependency probms prevent configuration of ssh: ssh depends on openssh-server; however: Package openssh-server is not configured yet. dpkg: error processing ssh (--configure): dependency problems - leaving unconfigured No apport report written because the error message indicates its a followup error from a previous failure. Errors were encounter while processing: openssh-server ssh E: Sub-process /usr/bin/dpkg returned an error code (1)
安装有问题的客户端版本会导致：
sudo apt-get install openssh-client=1:5.9p1-5ubuntu1.1 Reading package lists... Done Building dependency tree Reading state information... Done E: Version '1:5.9p1-5ubuntu1.1' for 'openssh-client' was not found
在缺乏背景知识的情况下修复它的各种尝试都失败了，例如
dpkg-reconfigure -a apt-get -f install
有人可以提出建议如何解决这个问题，可能需要更多我需要的信息吗？
如何将openssh更新（我猜失败）恢复或失去焦点，这样我就可以安装其他软件包了？
编辑：
apt-cache policy openssh-client是：
openssh-client: Installed: 1:5.9p1-5ubuntu1.4 Candidate: 1:5.9p1-5ubuntu1.4 Version table: *** 1:5.9p1-5ubuntu1.4 0 500 http://archive.ubuntu.com/ubuntu/ precise-updates/main amd64 Packages 100 /var/lib/dpkg/status 1:5.9p1-5ubuntu1.3 0 500 http://security.ubuntu.com/ubuntu/ precise-security/main amd64 Packages 1:5.9p1-5ubuntu1 0 500 http://archive.ubuntu.com/ubuntu/ precise/main amd64 Packages
为了完整性/etc/apt/sources.list ：
deb http://archive.ubuntu.com/ubuntu precise main restricted universe multiverse deb http://archive.ubuntu.com/ubuntu precise-updates main restricted universe multiverse deb http://archive.ubuntu.com/ubuntu precise-backports main restricted universe multiverse deb http://security.ubuntu.com/ubuntu precise-security main restricted universe multiverse
只需删除这些包，就可以将apt用于其他包。 在终端中执行此命令。
sudo apt-get remove openssh-server openssh-client --purge && sudo apt-get autoremove && sudo apt-get autoclean && sudo apt-get update
然后重新安装openssh服务器和客户端。
sudo apt-get install openssh-server openssh-client
删除/清除openssh-server和openssh-client时不能选择（例如当另一个包依赖于它们时）
这对我有用：
sudo dpkg -i /var/cache/apt/archives/openssh-*.deb sudo dpkg --configure -a
