活动：活动（退出）服务 plexconnect 开始退出

我已经安装了一个名为“plexconnect”的 python 脚本，它基本上是一个脚本，用来欺骗我的 Apple tv3 在别处寻找它的预告片。来源：https ://github.com/iBaa/PlexConnect

然后我做了一个初始化脚本。来源：https ://forums.plex.tv/discussion/156534/install-on-ubuntu-server

我对这个守护进程的（小）问题是在重新启动后服务总是以活动状态（退出）启动：

● plexconnect.service - LSB: This is the Plex Connect daemon
   Loaded: loaded (/etc/init.d/plexconnect; bad; vendor preset: enabled)
   Active: active (exited) since sø. 2016-03-27 14:29:27 CEST; 1min 14s ago
     Docs: man:systemd-sysv-generator(8)
  Process: 1043 ExecStart=/etc/init.d/plexconnect start (code=exited, status=0/SUCCESS)
    Tasks: 0 (limit: 512)

mars 27 14:29:27 lenox2 systemd[1]: Started LSB: This is the Plex Connect daemon.

在我重新启动服务后，它可以正常工作（运行）：

● plexconnect.service - LSB: This is the Plex Connect daemon
   Loaded: loaded (/etc/init.d/plexconnect; bad; vendor preset: enabled)
   Active: active (running) since sø. 2016-03-27 14:31:09 CEST; 1s ago

我试图停止 plexmediaserver 并重新启动 plexconnect 以检查是否存在依赖关系问题，但如果没有 plexmediaserver 它运行良好。我还尝试将 plexmediaserver 作为Required-Start 添加到初始化脚本中：

#Required-Start:  networking plexmediaserver

然后：

sudo update-rc.d plexconnect defaults
insserv: Service plexmediaserver has to be enabled to start service plexconnect
insserv: exiting now!

很明显我在这里需要帮助。我现在唯一的线索是重启后底部服务状态的额外 python 行。可能是python需要成为必需的开始吗？

编辑：

我一直在考虑将 sysvinit (plexconnect) 转换为 Upstart.conf，因为 plexconnect 是 Upstart.conf，但后来我发现 ubuntu 现在使用 systemd。

我现在遇到的问题是，由于某种原因，plexmediaserver 作为 Upstart 运行，当我尝试创建 Upstart plexconnect.conf 时，会发生这种情况：

initctl: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused

所以现在我更加困惑了……如果 16.04 不允许我更新 Upstart，plexmediaplayer 怎么会成为 Upstart 服务？（通过 Ubuntu 软件包安装）。
