[jaunty]python(<2.6)-based apps cannot meet dependencies

[ericjosepi]

Binary package hint: python-libtorrent

Hi!

I have a friendly bug-report for the Jaunty devs. After installing alpha 5, many python based apps cannot meet their requirements.

For background,

I have damn near every python library installed (2.5, 2.6, 3.0) so as to optimize compatibility. When trying to re-install Deluge (since it was removed from my install by a sudo apt-get dist-upgrade) i get the following output

eric@PwnBox-Alpha:~$ sudo apt-get install deluge

Is this a problem with my machine or a problem in the repo or where is the issue? I can provide more information upon request.

EDIT: This affects AWN plugins and compiz-settings-manager as well. Seems like python <2.6 based apps are not working so well now...

Cheers,
Eric

I concur. This needs to be rebuilt against Python 2.6, which might require adjusting debian/control dependencies as well.

[Fallen Andy (andrew-f-allen)]

Confirmed here , resulted from a Partial Upgrade to Jaunty this morning (Sat Feb 28 c.a. 12:00 UTC). Affected just Deluge (for me).

Andy.

[ericjosepi (cocacolaninja)]

So is there a solution here or just wait till the packages in the repository are rebuilt?

[Martin-Éric Racine (q-funk)]

Making a quick build check, it seems that debian/control incorrectly purports to support any current Python version. Meanwhile, ./configure only knows how to check up to Python version 2.5 and thus fails.

It seems that upstream has a newer 0.14.2 release that builds as-is, if the single patch in debian/patches/ is removed and the rest of the debian folder is kept as-is.

However, it seems that simply retooling this source package against 2.6 would fix it; the key seems to be to acquire a ./configure that also checks for python2.6 in addition to older releases.

[ericjosepi (cocacolaninja)]

Okay so... Basically we wait until the devs put newer ./configure files into the packages then?

[ericjosepi (cocacolaninja)]

This can be fixed by adding Deluge's PPA to your sources and installing from there. I think it's safe to assume their package will eventually be introduced into the main repo but for now it's a usable workaround.

[ericjosepi (cocacolaninja)]

Okay, Ignore my last post, I installed Deluge from their PPA and it crashed from the first time I tried to start it. Probably loading a bad python-libtorrent binary.

[Andrew Starr-Bochicchio (andrewsomething)]

I've emailed the Debian maintainer about this issue to see about his time frame for the 0.14.2 release. If he's going to package it soon, we can sync from Debian. If not, I'll patch the current package to build with python 2.6 or update it to 0.14.2 in Ubuntu directly.

Hi Andrew,

lt/0.14.2 is already packaged, actually sitting in the NEW queue[0], and I just
have to wait for it to be accepted by ftp-masters.

I don't know how much time it'll take to get out of NEW... maybe it'll bee too
late for Ubuntu sync. In any case, the source package is available at
mentors[1], in case you want (can?) do an upload for Ubuntu.

Anyway, it will be built against python 2.5, which is the current release in
Debian (python 2.6 is in NEW for experimental).

Please tell me if there is anything I can do.

Thanks for the quick reply Cristian. Glad to see that it's already
uploaded. The fact that it is built against python 2.5 in Debian won't
be a problem as Ubuntu imports the source packages and rebuilds them. I
just built libtorrent-rasterbar with python 2.6 and can confirm that it
successfully builds.

It looks like we're still going to need a Ubuntu patch for the packaging
to install to usr/lib/python*/dist-packages/ instead of
usr/lib/python*/site-packages/

Thanks,

Andrew

[Luca Falavigna (dktrkranz)]

Andrew, could you please prepare an update for this package? You could grab entry from mentors.debian.net (thanks Cristian for your work!) and transition it for Python 2.6. These changes would enter Debian soon because they will turn to Python 2.6 soon, so we can sync it later on.

Meanwhile, I'm subscribing motu-release to process this upload. I attach Changelog to weigh changes introduced (they required a SONAME bump which affects qbittorrent as rdependency).

[Andrew Starr-Bochicchio (andrewsomething)]

 Does my approach look right? setup.py is called in a makefile with no way to pass arguments directly to it in ./configure. It ignores the --prefix flag and installs to usr/local/lib/python2.6/dist-packages/ I manually move it to the right place in python-libtorrent.install to avoid having to patch the source to use "setup.py --install-layout=deb". It feels a little hackish, but it keeps the diff from Debian smaller...

libtorrent-rasterbar (0.14.2-1ubuntu1) jaunty; urgency=low

Ciao Luca,

lt/0.14.2 has just been accepted un unstable, in case you want to wait for a
sync and then patch it for python 2.6.

Thanks,

Andrew, could you please provide a patch with the "standard" method suggested for Python transition? They will be affected soon, so it could be useful for Cristian have an already working patch to apply when Debian will move to 2.6 by default.

[Andrew Starr-Bochicchio (andrewsomething)]

This version patches the upstream makefile to use "--install-layout=deb" I assume that's what you mean be "standard" method. If it is possible to do this simply in debian/rules, I don't know how. Any advise would be appreciated.

[Savvas Radevic (medigeek)]

No offense, but I've included a patch for Ubuntu, it doesn't include merging. :)

[Andrew Starr-Bochicchio (andrewsomething)]

For those interested, I have libtorrent-rasterbar 0.14.2 in my PPA for testing. I also have deluge using python 2.6 and qbittorrent rebuilt for the libtorrent SONAME bump.

https://edge.launchpad.net/~andrewsomething/+archive/ppa

[StefanPotyra (sistpoty)]

After a quick check, I'm ok with the new upstream version (including a SONAME bump), it seems to be very limited in effect of packages needed a rebuild.

[Andrew Starr-Bochicchio (andrewsomething)]

Just a heads up on the qbittorrent rebuild that will be need due to the SONAME bump, it doesn't build with qt 4.5. See upstream Bug 332470. Attached is a debdiff fixing this issue.

[Luca Falavigna (dktrkranz)]

I'm fine too, FFe granted.

[Iain Lane (laney)]

Looks good, uploading. Thanks for your contribution.

Please ensure that all rdepends are properly updated.

Thanks for the upload.

The following must be rebuilt as a result:

Qbittorrent - above (closes Bug #332470 as well)
Deluge - Bug #336229

[William King (quentusrex)]

Also, when building libtorrent 0.14.8 I found that it hit this error:

configure: error: Unable to find Boost.Python library, this is required to build python bindings.

Until I added this flag: --with-boost-python=boost_python-mt-py26
