No. It shouldn't. Unfortunately, PEP-440 describes a versioning scheme that is incompatible with the versioning long used in Debian and it's derivatives such as Ubuntu. As the PEP says, "The main reason to even have a standardised version scheme in the first place is to make it easier to do reliable automated dependency analysis." We already have another system to do that and python-apt is conforming to it.
If one were to conform to PEP 440, then the package would be incompatible with distro versioning requirements. Note: This is not general issue for Python packages. It is only a conflict for Debian/Ubuntu native packages like python-apt. ** Changed in: python-apt (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to python-apt in Ubuntu. https://bugs.launchpad.net/bugs/1445949 Title: Version does not conform to PEP440 Status in python-apt package in Ubuntu: Invalid Bug description: When looking for available python modules, pkg_resources issues the following warning: /usr/lib/python2.7/dist-packages/pkg_resources/__init__.py:2512: PEP440Warning: 'python-apt (0.9.3.11build1)' is being parsed as a legacy, non PEP 440, version.
