Notes on SABnzbd PPA on Raspbian

Post by sander » January 25th, 2014, 6:10 am

Raspbian is based on Debian Wheezy. That means you can use the SABnzbd PPA on Raspbian if you follow the instructions on http://forums.sabnzbd.org/viewtopic.php?f=16&t=9844. Because it's wheezy, and like the said instruction tells you, you should put "precise" in the command, just like this:

Code: Select all

echo "deb http://ppa.launchpad.net/jcfp/ppa/ubuntu precise main" | sudo tee -a /etc/apt/sources.list && sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:11371 --recv-keys 0x98703123E0F52B2BE16D586EF13930B14BB9F05F
HTH

-----------------------------------------------------------

Long / more details:


You can use the SABnzbd PPA on Raspbian, with just one small delta against the instruction on http://wiki.sabnzbd.org/install-ubuntu-repo

The line

Code: Select all

echo "deb http://ppa.launchpad.net/jcfp/ppa/ubuntu $(lsb_release -c -s) main" | sudo tee -a /etc/apt/sources.list && 
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:11371 --recv-keys 0x98703123E0F52B2BE16D586EF13930B14BB9F05F
did not work for me because of problems with the lsb_release command (see below). Workaround: just put in "precise", so:

Code: Select all

echo "deb http://ppa.launchpad.net/jcfp/ppa/ubuntu precise main" | sudo tee -a /etc/apt/sources.list && sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:11371 --recv-keys 0x98703123E0F52B2BE16D586EF13930B14BB9F05F
The rest of the instruction does work on Raspbian.

FWIW: Problems with lsb_release:

lsb_release is not installed by default on Raspbian. Install the package "lsb-release" (with a minus, not an underscore) to solve that. However, that won't help much:

Code: Select all

[email protected] ~ $ echo "deb http://ppa.launchpad.net/jcfp/ppa/ubuntu $(lsb_release -c -s) main" 
deb http://ppa.launchpad.net/jcfp/ppa/ubuntu n/a main
So: "n/a" as output? ???

FYI: Ubuntu says something like:

Code: Select all

$ lsb_release -c -s
saucy
Full lsb_release output on Raspbian:

Code: Select all

[email protected] ~ $ lsb_release -a
No LSB modules are available.
Distributor ID:	Debian
Description:	Debian GNU/Linux 7.2 (n/a)
Release:	7.2
Codename:	n/a
FWIW2: Result in /etc/apt/sources.list

Code: Select all

deb http://mirrordirector.raspbian.org/raspbian/ wheezy main contrib non-free rpi
deb-src http://mirrordirector.raspbian.org/raspbian/ wheezy main contrib non-free rpi

deb http://ppa.launchpad.net/jcfp/ppa/ubuntu precise main

The instructions for the ppa target only ubuntu. With anything else out there that uses dpkg there's only one thing to say: ymmv. The very possibility of using this ppa on debian is an exception to the rule: it would be impossible if sabnzbd's code wasn't completely architecture-independent or the packaging not kept at least somewhat compatible. In fact, if you were to go on some debian forum and proudly inform them of your success in using it, you'd be their favorite newbie of the week ...for target practice.

Sometimes helper programs such as add-apt-repository have been modified to get it right, for example by automatically translating their own release names back to the ubuntu equivalent on which they were based. For others such things may not even be present at all. There's simply no way to accurately predict all impact of modifications made by the many derivative distributions around. In case of raspbian, you're looking at a debian derivative. Therefore, best chances are probably with the instructions for updating sab on debian.

Thanks for pointing to http://forums.sabnzbd.org/viewtopic.php?f=16&t=9844. That instruction says: "For wheezy, substitute lucid with precise in the first command:"

Can that be changed to "For wheezy and raspbian, substitute lucid with precise in the first command:"?

If so, I can delete this thread, right?

I'd prefer to keep the other thread about debian, first and foremost. After all, raspbian is the name of an OS, not any specific verison of it; a future version of raspbian may well not be based on debian wheezy.

If you consider raspbian important/popular enough, just keep this thread (or a cleaned up version of it) and include a link to the debian instructions.

Fix the problems involving 'mathkernel' and/or 'minidlna' init scripts? You would probably have run into this with any package that installs a service...

The sabnzbdplus script has proper boot dependencies in its INIT INFO section, doesn't interact with either of those, and also doesn't depends on "system facility $all" (=start/stop after/before everything else):

Code: Select all

# Provides:          sabnzbdplus
# Required-Start:    $network $remote_fs
# Required-Stop:     $network $remote_fs
# Should-Start:      $named dbus avahi network-manager wicd
# Should-Stop:       $named dbus avahi network-manager wicd
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
Note that the Should-* indicates weak/optional dependencies. The "$network" facility assures basic networking such as creating the devices and setting up localhost is done, and "$remote_fs" is needed because the entire /usr tree (i.e. /usr/bin/sabnzbdplus) may be on a remote fs.

After remvoing sabnzddplus, a apt-get update/upgrade is clean. But I have the idea your post already implies that, and that the init script of another script interferes with sabnzbd?

I removed minidlna, but still errors. There is no package 'mathkernel', so I'll have to find which package provides that file. Ah, it contains this line:

Code: Select all

do_start () {

So Mathematica. I think it is installed by Raspbian (not by me).

Yup. Debian wheezy uses a dependency based boot sequence. As a result, every time a package installs a new system service, boot order must be examined in a process that involves all init.d services, not just the new one. This way, even scripts totally unrelated to the package you're installing at the time can cause breakage.

The interwebs claim mathematica gets installed by default on recent raspbian images, so I took a quick look at their init script only to find this mess: :-\ :-[ :'( :(

Code: Select all

#!/bin/sh

PATH=/sbin:/usr/sbin:/bin:/usr/bin

do_start () {
 (cat /usr/share/Mathematica/remotemode.m | /opt/Wolfram/Mathematica/10.0/Executables/wolfram) &
}

do_status () {
 echo "Process ID at: "
 cat /var/run/mathkernel.pid
 echo
 echo "MathLink located at: "
 cat /var/run/mathkernel.link
 echo
}

do_stop () {
 kill -9 `cat /var/run/mathkernel.pid`
 rm /var/run/mathkernel.pid
 rm /var/run/mathkernel.link
}

case "$1" in
  start|"")
	do_start
	;;
  restart|reload|force-reload)
	do_stop
	sleep 4
	do_start
	;;
  stop)
	do_stop
	;;
  status)
	do_status
	exit $?
	;;
  *)
	echo "Usage: mathkernel [start|stop|status]" >&2
	exit 3
	;;
esac

:
...including the complete lack of lsb headers or any other attempt at debian policy compliance, the casual use of 'kill -9' to stop a program and the extra ":" at the end. The wolfram-engine package doesn't even try to hook up the init script (then why is it there in the first place?!); if it did, its own install would probably fail. Instead, as you have seen, its mere presence causes insserv to fail (and thus failure of unrelated packages). Please file a bug report with raspbian and/or wolfram! A clusterfuck like this would be release-critical on debian.

Re: Notes on SABnzbd PPA on Raspbian

And could all this be solved by changing the /etc/init.d/mathkernel script? That would be it?

I can post the problem as described here (but then only wolfram-engine vs minidlna, not sabnzbd). In my experience, filing a bug leads to no reaction (Ubuntu: just each 6 month the automatic mail "can you check if it still happens in the new Ubuntu version" :-( ) or even hostility (Raspbian: "don't tell us how it should work"). So I can just post a FYI ... if I can reproduce it without SABnzbd.

EDIT:

I cannot reproduce it without sabnzbdplus: I removed sabnzbdplus, installed minidlna and wolfram-engine, after which the upgrade/upgrade cycle is still fine. After installing sabnzdplus, the problem as posted appears again. >:(

That makes it difficult for me to post it as a bug in wolfram-engine. I 100% believe you it is, but I will not be able to convince Raspbian people.

I googled "insserv: warning: script 'mathkernel' missing LSB tags and overrides" and it points to http://www.raspberrypi.org/forum/viewto ... 6&p=476956

http://www.raspberrypi.org/forum/viewto ... 52#p476952 says to run "dpkg -P minidlna", which removes minidlna. Yes, that's a way to get rid of an error message ... :-(

EDIT:

some more googling leads to http://www.forum-raspberrypi.de/Thread- ... -overrides

So, in /etc/init.d/mathkernel after #!/bin/sh I added

Code: Select all

### BEGIN INIT INFO
# Provides:          mathkernel
# Required-Start:    $local_fs 
# Required-Stop:     $local_fs
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: mathkernel
### END INIT INFO
and the update/upgrade is clean. Or, in plain German: "und dann mault die Installation auch nicht mehr." :D

To be complete, as the poster says: "Ob für mathkernel das Filesystem tatsächlich oben sein muss , weiß ich nicht. Aber es schadet nichts."

Fair enough. Just tried to do some closer examination on a debian unstable vm, turns out minidlna is a in a rather disastrous state too: uninstallable, removed from debian testing and full of security holes. Nothing much left to test. Maybe it's minidlna's init script apparently trying to start/stop as late/early as possible by soft-depending on "$all" that triggers this stuff, not the still ridiculous mathkernel script. Either way, I'm fairly certain sab is just getting caught in the crossfire here.

Did you try to install anything with an init script (other than sab) with those two installed? ('apt-file search etc/init.d' for a selection) [never mind, your latest post pretty much answer this one]


Edit: from what I can tell, the mathkernel script never actually does anything other than take up disk space and/or get in the way. So rendering it harmless (all comments, no content) like your german connection did is probably best.

Don't have one.Thanks for the offer, but my todo list is getting longer by the day already, so I'd prefer not to spend yet more time on bug hunting in packages I don't maintain myself for now.
