apt-get升级期间的断电破坏了apt-get命令。

Question

我有一个运行Ubuntu18.04LTS的服务器。今天早上，我运行了一个apt upgrade，在运行过程中，服务器失去了动力。一旦它被恢复，我登录并注意到有两个软件包“没有完全安装或删除”。我试着运行apt-get autoremove、显式apt-get remove命令，并在网上找到了许多我现在不记得的解决方案。

似乎什么都没有帮助，而且我无法升级/安装软件包，因为我对损坏的软件包有很大的错误。它们是内核包：

linux-image-4.15.0-50-generic
linux-image-4.15.0-51-generic

下面是apt-get autoremove的输出：

Reading package lists... Done

The following packages will be REMOVED:

0 upgraded, 0 newly installed, 1 to remove and 0 not upgraded.
3 not fully installed or removed.

在手动删除apt-get autoremove文件之后运行一系列.deb和apt-get autoclean命令似乎已经清除了它。
