Bug#598432: python-apt: upgrade fails

[Stefan Fleischmann <dubliner@gmx.net>]

Just to clarify, the "quick fix" I posted here was supposed to help people to
get rid of the buggy package. It doesn't fix the actual package.

Like I said before, the problem is not only the version number handling by
pycentral but also the path of the installed files! If you have look at the
package 0.7.97.1 for amd64 or 0.7.98 for i386 you'll see that files are put
in /usr/lib/python3.1
In this package however files are put in /usr/lib/python3 instead which causes
the problem you describe when simply changing the version number to 3.1.

If you think pycentral should handle integer version numbers (at least it
shouldn't exit with an error I guess) please file a bug report there.

But to summarize for this package I think the files are put in the wrong place
(compared with the package from testing and packages for i386) and the version
number in the mentioned config file is wrong.

If you want this package to work you'll have to extract it, rename the folder
usr/lib/python3 to python3.1 and also change this path and the version number
to 3.1 in usr/share/pyshared-data/python-apt. Then rebuild the package.
But having a fixed version doesn't help you getting rid of the package from the
system because dpkg won't remove it due to the prerm script which executes
pycentral and fails.
So the easiest thing to do is simply changing the 3rd line in
/usr/share/pyshared-data/python-apt to "python-version = 2.6, 3.1, 2.5" and
then you can replace the package.
