我无法使用关闭命令，因为系统“无法连接到总线：没有这样的文件或目录”

Question

如果我使用该shutdown命令，我的系统会抛出错误。即使我使用shutdown -h或shutdown -h now

user@Domain:~$ sudo shutdown
[sudo] password for user:
Failed to connect to bus: No such file or directory
Failed to connect to bus: No such file or directory
user@Domain:~$ shutdown -h
Failed to connect to bus: No such file or directory
Failed to connect to bus: No such file or directory
user@Domain:~$ shutdown -h now
Failed to connect to bus: No such file or directory

我可以开始工作的唯一命令是 sudo shutdown -h now

这是预期的行为吗？

dbus 已安装并且是最新的...

user@Domain:~$ sudo apt-get install dbus
[sudo] password for user:

事实证明，问题出在dbus- 即使它已经安装并且是最新的，它仍然被破坏了。

你可以重新安装它

apt-get install --reinstall dbus
