我正在运行 Ubuntu 12.04 服务器版本（静态 LAN IP），并尝试按照此处的说明使用 apt 安装 SABnzbdplus： Ubuntu PPA 存储库
安装进展顺利，服务器下载等都没有问题！问题是我按照提供的说明编辑了 /etc/default/sabnzbdplus：
# This file is sourced by /etc/init.d/sabnzbdplus
#
# When SABnzbd+ is started using the init script, the
# --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=omar
# [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=8080
# [optional] extra command line options, if any:
EXTRAOPTS=
我的（omar）运行级别是 N 2。
不太确定该做什么，因为执行：/etc/init.d/sabnzbdplus 工作正常且没有错误。
不知道该怎么做。非常感谢您的建议和帮助！
谢谢，
