And BTW: shouldn't we fork this to a separate thread, like "SABnzbd on python 2.6"?

Worst case, the bug reports get closed as invalid. Probably best to create separate ones for each affected package.

Anyway, just uploaded a new revision for jaunty that eases restrictions on the python version to allow anything over 2.4. No guarantees it will install just yet - dependencies such as cheetah may still block things - or work properly. In case the program fails to enjoy python 2.6, you could edit the first line in /usr/bin/sabnzbdplus to point to "/usr/bin/python2.5" directly so it would run under 2.5 regardless.

I've tried some brute force installation, but so far it's not something nice.

Code: Select all

  wget http://nl.archive.ubuntu.com/ubuntu/pool/universe/c/cheetah/python-cheetah_2.0.1-2_i386.deb
  wget http://nl.archive.ubuntu.com/ubuntu/pool/universe/p/python-yenc/python-yenc_0.3+debian-2.deb
  sudo dpkg --ignore-depends=python  -i python-cheetah_2.0.1-2_i386.deb 
  sudo dpkg --ignore-depends=python  -i python-yenc_0.3+debian-2_i386.deb

That seemed to work. However, after that, installing anything is impossible:

Code: Select all

sander@jaunty:~$ sudo apt-get install par2
Reading package lists... Done
Building dependency tree       
Reading state information... Done
You might want to run `apt-get -f install' to correct these:
The following packages have unmet dependencies:
  python-cheetah: Depends: python (< 2.6) but 2.6.1-0ubuntu1 is to be installed
  python-yenc: Depends: python (< 2.6) but 2.6.1-0ubuntu1 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
sander@jaunty:~$ par2
The program 'par2' is currently not installed.  You can install it by typing:
sudo apt-get install par2
bash: par2: command not found
sander@jaunty:~$

And that 'apt-get -f install' just wants to remove cheetah and yenc:

Code: Select all

sander@jaunty:~$ sudo apt-get -f install

In other words: this method messes up the installation system. :-(

I tried another method: let Ubuntu remove the conflicting cheetah and yenc, then install the other pacakages, then force install cheetah and yenc:

Code: Select all

sudo apt-get -f install
sudo apt-get install python python-cherrypy python-elementtree  python-celementtree python-feedparser unrar unzip par2 python-openssl
sudo dpkg --ignore-depends=python  -i python-cheetah_2.0.1-2_i386.deb 
sudo dpkg --ignore-depends=python  -i python-yenc_0.3+debian-2_i386.deb

After that, I changed the first line of SABnzbd.py to:

Code: Select all

#!/usr/bin/python2.5 -OO
###  !/usr/bin/python -OO

After that I was able to run SABnzbd:

Code: Select all

Of course, package management is still messed up: ubuntu wants to remove cheetah and yenc.

shypike said "One problem is that Cheetah and yEnc need the C compiler, meaning we cannot just patch and embed them.", so that means they can't be included in SABnzbd utils?

Exactly, these contains "extensions", c-code that must be compiled against the specific python install on a system. Brute-forcing the cheetah and yenc installs will never work with python 2.6 for that reason, these packages were built before that was available and therefore simply cannot support 2.6.

Your only chance, other than waiting for ubuntu to update theirs, is to rebuild them yourself from sources on jaunty. In short, install devscripts, enable source repositories, apt-get build-dep , apt-get source , cd into the newly created dir , run debuild there. If it succeeds, the resulting debs will be in the parent dir. Still no guarantee they will work with 2.6 without changes to the packaging (in particular, certain python version may be blocked via debian/pyversions or XS-Python-Version var in debian/rules because the code is known not to work).

I've reported the python-cheetah bug: https://bugs.launchpad.net/ubuntu/+sour ... bug/336192 titled "cannot install python-cheetah on Jaunty Alpha 5: unmet dependencies"

Let's see what happens.

As python2.5 is still available, can't we install / copy python-cheetah (for python 2.5) to a separate, non-system directory, and then import that directory into SABnzbd.py (using python2.5) with an absolute path?

I've report a bug on python-yenc with Ubuntu Jaunty Alpha 5 too.

See https://bugs.launchpad.net/ubuntu/+sour ... bug/336415 titled "cannot install python-yenc on Jaunty Alpha 5: unmet dependencies".

@jcfp: thanks for confirming the python-cheetah bug on launchpad.

Seems to be working fine after latest update.

Thanks guys.

edit:

Maybe this is of some importance to you developers:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

The following packages have unmet dependencies:

Without python-yenc I'm able to start and use SABnzbd 0.4.7, but with a warning:

Code: Select all

2009-03-02 19:14:52,361::INFO::_yenc module... NOT found!

Question: does SAB really need yenc? I was able to download a post that had "yEnc" in the title.

Posted: **March 2nd, 2009, 3:34 pm**

Python-yenc update probably hasn't made it to the archives yet, expect it within 24 hours. It's faster than having hte same functionality as pure python code, but sabnzbd if necessary can live without it; that's why it is recommended and not a hard depend in the first place. That "DeprecationWarning" as posted by razor1394 is rooted in cherrypy's code, not sabnzbd.

Thanks for all the feedback, keep it coming especially with regard to the behaviour and performance of the program when running under python 2.6 on jaunty.

Sorry for a beginners question but how do I upgrade only SABnzbd and not my whole system?
I did:

Code: Select all

sudo apt-get update
...
sudo apt-get upgrade
..
/etc/init.d/sabnzbdplus restart

And all seems working fine but I got 50Mb of all kinds of libs and to me seemingly irrelevant things upgraded.

Cheers and thanks for great work!

Indeed: after today's update, I can install python-yenc, and thus SABnzbd / sabnzbdplus.

So the Ubuntu 9.04 package stuff is solved now. That's fast!

AFAIK the only remaining thing is the time-out / non-response after Save Changes (caused by python 2.6 or one of the packages). To me, that seems a minor bug: the workaround is just pressing the web browser's Reload-button a few seconds after pressing Save Changes.

Probably doable by not using 'apt-get upgrade', but instead just 'apt-get install '. Not recommended though, updates are hard enough to get approved and thus not very likely to be "irrelevant", especially the ones from Ubuntu's own repositories.

That's caused by some code that is part of the sabnzbd releases not working with python 2.6, shutdown from the web interface also doesn't respond and probably a few more things. The latest version for jaunty has been patched to use python2.5 exclusively, avoiding any such issues.

So everything is solved now for Ubuntu 9.04 Jaunty?
And "dare devils" can still try out SAB 0.4.x on python 2.6 by running the standard SABnzbd or by changing the first line of sabnzbdplus again.

Cool!
