我想在我的服务器上安装 openssh-server，但它显示：

openssh-server is already the newest version.
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
upstart : Depends: ifupdown (>= 0.6.10ubuntu5)
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

任何想法 ？
答案1
您可能想尝试清除安装并清理一下 apt。
尝试：
sudo apt-get remove openssh-server openssh-client --purge && sudo apt-get autoremove && sudo apt-get autoclean && sudo apt-get update
如果您没有任何理由不升级软件包，也可以尝试：
sudo apt-get dist-upgrade
然后，您可以尝试再次安装软件包，看看是否解决了问题：
sudo apt-get install openssh-server openssh-client
编辑：
注意到ubuntu错误中引用了：upstart : Depends: ifupdown (>= 0.6.10ubuntu5)
检查您的sources.list文件和sources.list.d目录文件中是否有对ubuntu.如果有则将其注释掉并再次尝试上述命令。
如果安装了任何ubuntuPPA 或ubuntu.deb 软件包，也可能会导致问题。
答案2
特别感谢你们所有人，我将其更改sources.list为：
deb http://deb.debian.org/debian/ oldstable main contrib non-free
deb-src http://deb.debian.org/debian/ oldstable main contrib non-free
deb http://deb.debian.org/debian/ oldstable-updates main contrib non-free
deb-src http://deb.debian.org/debian/ oldstable-updates main contrib non-free
deb http://deb.debian.org/debian-security oldstable/updates main
deb-src http://deb.debian.org/debian-security oldstable/updates main
deb http://ftp.debian.org/debian wheezy-backports main
deb-src http://ftp.debian.org/debian wheezy-backports main
我认为它有效，oldstable这很重要。
