stop: Job failed while stopping start: Job is already running: networking eth0 not configured

再給ubuntu系統重啟網絡服務的時候出現失敗，“stop: Job failed while stopping start: Job is already running: networking”

試了好幾種方法都不行一直失敗，不知道是什么原因導致。

void@void-ThinkPad-E450:~$ sudo service networking restart
stop: Job failed while stopping
start: Job is already running: networking

void@void-ThinkPad-E450:~$ sudo ifdown eth0
ifdown: interface eth0 not configured

void@void-ThinkPad-E450:~$ sudo NetworkManager restart
NetworkManager is already running (pid 1708)

最后因為已經知道了進程的pid號，所以可以直接用kill命令結束進程，然后重新啟動服務得以解決。
