Ubuntu 16.04 无法关机：poweroff.target 已被禁用

Ubuntu 16.04 无法关机。当我转到屏幕右上角的图标并单击关机时，它不会关机。我运行了shutdown -h now，结果如下：

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:

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)

我不知道为什么会发生这种情况，也不知道该如何解决。如能得到任何帮助，我将不胜感激。

通过输入此命令启用“poweroff.target”的 systemd 服务应该可以解决该问题：

systemctl enable poweroff.target
