我的机器上的 openssh-server 似乎出了问题。我在 Ubuntu 20.04 上。我在尝试安装另一个依赖于 openssh-server 的软件包时注意到了这一点。
当我尝试重新安装时，它说正在配置“部分安装的包”，所以我想我一定是错过了上次升级时这个包发生的某些事情。

建议寻找更多详细信息的地方对我来说似乎没有特别有用的信息。

aptitude remove openssh-server运行并尝试重新安装后，我遇到了同样的错误。有什么想法可以尝试下一步吗？
我的ubuntu版本：
andy@andy-UX303UA:~$ lsb_release -a
LSB Version: core-11.1.0ubuntu2-noarch:security-11.1.0ubuntu2-noarch
Distributor ID: Ubuntu
Description: Ubuntu 20.04.2 LTS
Release: 20.04
Codename: focal
答案1
我不知道是否aptitude remove清除了配置，手册页在我看来不太清楚。aptitude remove openssh-server您可以尝试apt-get purge openssh-server重新安装该软件包。
如果这没有帮助，您可以尝试获取有关此错误的更多信息：
dpkg: error processing package openssh-server (--configure):
installed openssh-server package post-installation script subprocess returned error exit status 1
了解安装后脚本失败的原因会很有帮助。在（重新）安装软件包后，您可以运行dpkg-reconfigure openssh-server。我认为这值得一试，因为与使用 aptitude 包装相比，单独执行此步骤可能会提供更多信息。
