问题描述
Ubuntu 16.04 不会关机。当我转到屏幕右上角的图标并单击关机时，它没有关机。我运行了 shutdown -h now，这就是我得到的：
tanner@tanner-x151x:~$ shutdown -h now
Failed to set wall message, ignoring: Interactive authentication required.
Failed to power off system via logind: Interactive authentication required.
Failed to start poweroff target: Interactive authentication required.
See system logs and 'systemctl status poweroff.target' for details.
Failed to open /dev/initctl: Permission denied
Failed to talk to init daemon.
tanner@tanner-x151x:~$ sudo shutdown -h now
[sudo] password for tanner:
Failed to start poweroff target: Transaction is destructive.
5ee system logs and 'systemctl status poweroff.target' for details.
tanner@tanner-x151x:~$ sudo halt now
Too many arguments.
tanner@tanner-x151x:~$ systemctl status poweroff.target
poweroff.target - Power-off
Loaded: loaded (/lib/systemd/system/poweroff.target; disabled; vendor preset:
Active: inactive (dead)
Docs: man:systemd.special(7)
我不知道为什么会这样或如何解决这个问题。任何帮助，将不胜感激。
最佳方案
这有点残酷，但你可以试试：
\\n
sudo poweroff -f
\\n

次佳方案
输入此命令以启用 “poweroff.target” 的 systemd 服务应该可以解决此问题：
systemctl enable poweroff.target
