This renders the > package uninstallable. After taking a first look at the code, I've got the feeling that dh_python2 is fundamentally broken for packages that don't use the default python version. In case that X-Python-Version is set to a fixed version (e.g. '2.6'), options.vrange has value ((2, 6), (2, 6)). Given to Dependencies.parse() from debpython/depends.py, this results in the ambiguous dependency on 'python (>= 2.6.6-7~), python (<< 2.6)'. The first problem is that Dependencies.parse() uses the second tuple from vrange as maximum python version, but returns '(<< X.X)'. I guess that this should rather be '(=< X.X)'. The second problem is much more general: I don't see why the versioned depends on python are added at all. If the package has X-Python-Version set to '2.6', this should result in a dependency on 'python2.6', which might be versioned if required. But adding a dependency on 'python (>= MIN), python (=< MAX)' makes no sense to me. Once the default python version is bumped to a new major version, the package will be rendered uninstallable. This might make sense for packages which use the default python in shebang - but require a special version. But for packages which take care of the python version in shebang, a dependency on pythonX.X would be sufficient. Maybe I'm totally wrong. Please bear with me in that case. It's the first time that I look into the dh_python2 code.
