“处理包时出错” - 由于包配置错误，apt升级无法运行

Question

我知道之前已经被问过很多次了，但这些解决方案都没有帮助我。

每次我运行时sudo apt upgrade都会出现此错误。

dpkg: error processing package systemd (--configure):
 installed systemd package post-installation script subprocess returned error exit status 127
Errors were encountered while processing:
 systemd
E: Sub-process /usr/bin/dpkg returned an error code (1)

并sudo dpkg --configure -a返回

  Setting up udev (237-3ubuntu10.28) ...

systemd我认为一起删除软件包并不安全。感谢任何帮助，我使用的是 Ubuntu 18.04。

和

stat / /dev /var

检查您是否是所有目录的所有者。如果没有，请运行：

chown root DirectoryYouAreNotOwner

就我而言， 的所有者/ 是Unknown. 所以我使用了命令：

chown root /
