Comment 6 for bug 121341

It does not just affect apport, but also restricted-manager, update-manager, update-notifier, and all other Python packages.

I do not quite understand your reply. "Extension modules" are compiled ones which need to exist per-version, right? But those need separate paths per version anyway? I was just talking about the Python modules (.py files) which are version independent. Right now they are linked to two different places (once for each supported Python version), and those symlinks (or rather, removing them during upgrades) are the bit that cause the pain.

What do you mean with "adding two locations for the same package"?
