[Python-modules-team] Bug#700718: python-numpy: fails to upgrade from squeeze: prerm: 6: update-python-modules: not found

[Andreas Beckmann]

Package: python-numpy
Version: 1:1.6.2-1.1
Severity: serious
User: debian-qa at lists.debian.org
Usertags: piuparts

Hi,

during a test with piuparts I noticed your package fails to upgrade from
'squeeze'.
It installed fine in 'squeeze', then the upgrade to 'wheezy' fails.

>From the attached log (scroll to the bottom...):

  Preparing to replace python-numpy 1:1.4.1-5 (using .../python-numpy_1%3a1.6.2-1.1_amd64.deb) ...
  /var/lib/dpkg/info/python-numpy.prerm: 6: update-python-modules: not found
  dpkg: warning: subprocess old pre-removal script returned error exit status 127
  dpkg: trying script from the new package instead ...
  /var/lib/dpkg/tmp.ci/prerm: 6: update-python-modules: not found
  dpkg: error processing /var/cache/apt/archives/python-numpy_1%3a1.6.2-1.1_amd64.deb (--unpack):
   subprocess new pre-removal script returned error exit status 127
  configured to not write apport reports
  /var/lib/dpkg/info/python-numpy.postinst: 6: update-python-modules: not found
  dpkg: error while cleaning up:
   subprocess installed post-installation script returned error exit status 127

Note that the attached log is from a squeeze -> sid upgrade, but I
manually ran piuparts to test squeeze -> wheezy(+new numpy) upgrades
which failed with exactly the same error.

This was observed while testing the upgrade of sixpac [contrib] from
squeeze, but I have now rescheduled all tests that might be affected by
the last mumpy upload ...


cheers,

Andreas
