This appears to be a problem with python-central.
What version of python-central have you installed? (you can see this with e.g. "dpkg -s python-central")

Re-assigning to apport. From the changelog, it switched to python-central in 0.102 and you're trying to upgrade from 0.101 to 0.103.
I haven't experienced this problem, but have upgraded to 0.102 before.. maybe there's the problem?

Finally I was able to upgrade to 0.103 by installing 0.102 first

wget http://archive.ubuntu.com/ubuntu/pool/main/a/apport/apport_0.102_all.deb
dpkg -i apport_0.102_all.deb

Re-assigning to python-central: this appears to happen if the currently installed version has no Python-Version header (in "dpkg -s"), but the version being installed expects it to have one. I've only took a quick look at the code yesterday, so don't rely on my info, please..
