Quickfix: libroot-python-dev for Ubuntu Gutsy

Since my last post on building ROOT packages for Ubuntu the resourceful Christian Holm Christensen has got the unofficial Debian/Ubuntu ROOT repository back online. One problem is that due to a dh_python bug in Ubuntu, the libroot-python-dev package (required for PyROOT) is broken for Gutsy (and probably Feisty too), since it depends on python < 2.5. I’ve hacked the ‘control’ file to remove that broken dependency and repacked the .deb file to make a package that is installable and doesn’t break apt.

Download it here:

Steps to create this:

  • Get the libroot-python-dev package from the repository
  • Unpack the .deb
    ar -x libroot-python-dev_5.17.05-3_i386.deb
  • Unpack the control data:
    tar -zxf control.tar.gz
  • Edit the file ‘control’ to fix the dependencies and bump the version number
  • Repack control data:
    tar -zcf control.tar.gz control md5sums postinst prerm
  • Repack the .deb
    ar -r libroot-python-dev_5.17.05-3-quickfix_i386.deb debian-binary control.tar.gz data.tar.gz

I hope to help fix the underlying issue soon but right I’ve got a ton of thesis-related work to plough through so this band-aid will have to do for now.

Update 2007-12-11:
I spent a morning last week tracking down this ROOT Python bug. Turns out there was a file not being deleted during the ‘clean’ stage of the debian package creation which led to a dependency confusion with python versions. New source packages have been uploaded which fix this issue:
deb-src unstable main contrib

Binary packages should be up shortly.

Update 2009-03-02:

Noticed a typo in the re-tarring command, now fixed.
