dapper->hardy upgrade fails

[Michael Vogt]

Binary package hint: python-central

On a dapper -> hardy upgrade test with huge amounts of packages installed, python-central gives the following error:

Setting up python-central (0.6.0ubuntu2) ...^M
pycentral: pycentral pkginstall: not overwriting local files^M
pycentral pkginstall: not overwriting local files^M
dpkg: error processing python-central (--configure):^M
 subprocess post-installation script returned error exit status 1^M

This system never had local files, its a stock dapper install with additional packages from main.

Additional debug output of the maintainer script that may help finding the problem:

In a dapper pbuilder chroot with just python-pyrex installed, the upgrade gives me the following error:

Preparing to replace python-pyrex 0.9.3.1-2ubuntu2 (using .../python-pyrex_0.9.6.4-1build1_all.deb) ...
Unpacking replacement python-pyrex ...
dpkg: error processing /var/cache/apt/archives/python-pyrex_0.9.6.4-1build1_all.deb (--unpack):
 trying to overwrite `/usr/bin/python2.4-pyrexc', which is also in package python2.4-pyrex
dpkg-deb: subprocess paste killed by signal (Broken pipe)

[Michael Vogt (mvo)]

I will upload a new python-pyrex with the missing replaces, but I'm not sure if that will fix the python-central issues were it reports "not overwriting local files".

[Michael Vogt (mvo)]

This should be fixed now in the current python-pyrex
