因此，我的电源在更新过程中断了，
并且sudo dpkg --configure -a只是告诉我有关错误，它无法自动修复某些systemd:amd64东西。
这就是我要做的全部工作：
sudo dpkg --configure -a
dpkg: dependency problems prevent configuration of libnss-systemd:amd64:
libnss-systemd:amd64 depends on systemd (= 237-3ubuntu10.42); however:
Package systemd is not installed.
dpkg: error processing package libnss-systemd:amd64 (--configure):
dependency problems - leaving unconfigured
dpkg: dependency problems prevent configuration of libpam-systemd:amd64:
libpam-systemd:amd64 depends on systemd (= 237-3ubuntu10.42); however:
Package systemd is not installed.
dpkg: error processing package libpam-systemd:amd64 (--configure):
dependency problems - leaving unconfigured
Errors were encountered while processing:
libnss-systemd:amd64
libpam-systemd:amd64
老实说...我真的不知道从哪里开始。
Package systemd is not installed我的意思是，如果我只是从表面上理解错误信息，
那么我就会简单地尝试apt-get install systemd，
但我有点怀疑它可能会更复杂
（“如果该工具足以自动诊断问题，那么它是否应该足以使固定它会自动恢复吗？”），
而且我不想冒险让事情变得更糟，
所以我认为我应该先找个人确认一下。
我该怎么办？
