肯定有什么东西混乱了，它与dpkg有关。不知道是什么引起的。以下是症状:
sudo apt upgrade、sudo apt install <any package>、sudo apt remove <any package>、sudo apt install -f命令均失败，错误如下:
Setting up dpkg (1.21.1ubuntu2.1) ...

dpkg: error processing package dpkg (--configure):
installed dpkg package post-installation script subprocess returned error exit status 1
Errors were encountered while processing:
dpkg
sudo apt update运行正常
这是sudo dpkg --configure -a的输出，虽然我没有技术知识如何使它的意思的头或尾:

我在一个类似的主题上看到了另一个线程，建议stat / /dev /var的输出可能是有用的(虽然我不确定是什么)。

运行sudo chown root /没有任何影响。

提前感谢!
通过运行sudo mv /var/lib/dpkg/info/dpkg* /tmp，然后是sudo apt install -f和sudo dpkg --configure -a来解决我自己的问题。
请阅读https://itsfoss.com/dpkg-returned-an-error-code-1/，了解其工作原理。
所以，这个答案不会是最有帮助的，但是我今天遇到了一个类似的问题，在那里'out of the blue'我得到了关于一些软件包尚未配置的消息。
命令sudo apt install -f最初不起作用。只有在我运行了sudo dpkg --configure -a和前一个命令之后，一切才看起来正常。
这对我来说仍然是个谜，这一切是如何发生的，但我很高兴Mblizzard找到了解决方案，这在我的情况下也有效。谢谢!
注意:我使用的是Pop!_OS 22.04和我注意到麻烦的第一个迹象，当Pop!_Shop应用程序将不再更新安装的应用程序。然而，它却在没有任何通知的情况下关闭了。
在/var/lib/dpkg中可能有一个符号链接，名称为dpkg，指向这个文件夹。在配置前删除它有助于
