Add role account

useradd --system --shell /bin/false --no-create-home --home /home/sabnzbd sabnzbd
ln --symbolic /usr/src/sabnzbd /home/sabnzbd

Download source

cd /usr/src/
git clone git://github.com/sabnzbd/sabnzbd.git
chown --recursive sabnzbd:sabnzbd sabnzbd

Install dependencies

apt-get install python python-cheetah python-configobj python-feedparser python-dbus python-openssl python-support python-yenc par2 zip

unrar (non-free version)

In order to install the non-free version of unrar, you will need to have non-free defined in /etc/apt/sources.list

/etc/apt/sources.list

deb http://http.us.debian.org/debian wheezy main contrib non-free

apt-get update

You should see the non-free version now when you search for unrar

apt-cache search unrar

unrar - Unarchiver for .rar files (non-free version)

apt-get install unrar

par2 (experimental replacement)

You can get a dramatic performance increase while repairing archives by using a multithreaded version of par2.

cd /usr/src
wget 'http://chuchusoft.com/par2_tbb/par2cmdline-0.4-tbb-20100203.tar.gz'
tar -xvzf par2cmdline-0.4-tbb-20100203.tar.gz
cd par2cmdline-0.4-tbb-20100203
sed -i '1s/^/#include <memory>\n/' {par2cmdline,commandline,par2creator,par2repairer}.cpp
ln -s /usr/bin/aclocal /usr/bin/aclocal-1.10
ln -s /usr/bin/automake /usr/bin/automake-1.10
apt-get install libtbb-dev
./configure
make
strip par2
mv /usr/bin/par2 /usr/bin/par2.bak
mv par2 /usr/bin

Install init scripts

cp sabnzbdplus.init /etc/init.d/sabnzbdplus
cp sabnzbdplus.default /etc/defaults/sabnzbdplus
chmod +x /etc/init.d/sabnzbdplus

Start

/etc/init.d/sabnzbdplus start

Configure

SABnzbd+ can be configured remotely with the help of port forwarding.

ssh -L 8080:localhost:8080 <server>

Opening a browser to http://localhost:8080 should present you with the Quick-Start Wizard

Add it to default runlevel

Updating

Due to the way sabnzbd development occurs, master is always a stable branch.

Updating is as simple as:

cd /usr/src/sabnzbd
sudo -u sabnzbd git pull

Then restart the sabnzbd daemon with

/etc/init.d/sabnzbdplus restart

Nice, thanks!

PS: small typo i think: cp sabnzbdplus.default /etc/default s /sabnzbdplus

David's comment above it accurate, and needs to be corrected in the text. Otherwise, great tutorial.

I would add that many of these commands require sudo to be run.

If your init script terminates with no output then it's probably exiting at line 30 which (I think) means either your daemon (SABnzbd.py) is not executable or your settings are not readable.

In my case I had sab source code on a drive which had been mounted with rw,user options, which means it ends up in /etc/mtab with the noexec flag.
