ubuntu 20.04 上 openssh-server 的问题

Question

我的机器上的 openssh-server 似乎出了问题。我使用的是 Ubuntu 20.04。\n我注意到它试图安装另一个依赖于 openssh-server 的软件包。

\n

当我尝试重新安装时，它说它正在配置“部分安装的软件包”，所以我想我一定在之前的升级中错过了该软件包发生的事情。

对于我来说，建议的寻找更多细节的地方似乎并没有提供特别的信息。

运行后我遇到了同样的错误aptitude remove openssh-server，然后尝试重新安装它。有什么想法下一步要尝试什么吗？

Answer 1

我不知道是否aptitude remove清除配置，手册页在我的理解中不是那么清楚。aptitude remove openssh-server您可以尝试然后apt-get purge openssh-server再次安装该软件包。

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。（重新）安装该软件包后，您可以运行dpkg-reconfigure openssh-server. 我认为值得一试，因为与通过 aptitude 包装相比，单独执行此步骤可能会提供更多信息。
