新安装的服务无法在启动时启动

Question

我已经安装sabnzbd并能够运行service sabnzbdplus start和service sabnzbdplus stop启动和停止该程序，没有任何问题。它的配置文件在/etc/default和中/etc/init.d。我确实注意到我的 plex 服务器在中有一个附加文件，/etc/init而在sabnzbd中没有。我了解了运行级别，rc2.d文件夹中也有一个S98sabnzbdplus文件。我的运行级别是 2。

以下是输出lsb_release -a; uname -a; apt-cache policy sabnzbdplus：

以下是该文件的内容/etc/default/sabnzbdplus：

# --daemon option is always used, and the program is
# started under the account of $USER, as set below.
#
# Each setting is marked either "required" or "optional";
# leaving any required setting unconfigured will cause
# the service to not start.

# [required] user or uid of account to run the program as:
USER=Joshr

# [optional] full path to the configuration file of your choice;
#            otherwise, the default location (in $USER's home
#            directory) is used:
CONFIG=

# [optional] hostname/ip and port number to listen on:
HOST=0.0.0.0
PORT=4000

# [optional] extra command line options, if any:
EXTRAOPTS=

以下是该命令的输出grep 'Joshr' /etc/passwd

Joshr:x:1000:1000:Joshr,,,:/home/Joshr:/bin/bash

昨天我尝试将service sabnzbdplus start命令添加到脚本文件中，手动执行脚本时运行良好。然后我在文件中添加了对该脚本的调用/etc/rc.local，但在启动时仍然不起作用。
