Python2.7 transition and missing DialogAptKey in software-properties-gtk

Binary package hint: gapti

gapti, as it currently stands in Ubuntu, hardcodes a Python version dependency on 2.6.

There is a new upstream version (which was targetted at jaunty in LP: #340901) which would help here (it improves the packaging a lot).

I've taken the liberty of improving it further (Use dh_python2, dh7 minimal rules), and have uploaded a proposed branch to lp:~stefanor/gapti/py27transition.

gapti (0.0.3ubuntu1) natty; urgency=low

  [ Savvas Radevic ]
  * Bug-fix release.
  * python 2.6 transition (LP: #340901)
    + debian/control: Build-Depends: python-dev, python-support
    + gapti-root: Fixed UpdateManager.SimpleGladeApp
    + Edited files directly, shebangs: #!/usr/bin/python
    + Modified files directly using: 2to3-2.6 -w *
    + Replaced commands.getoutput with subprocess.Popen().communicate()
    + Replaced lines with spaces (\s+) with empty lines
  * debian/control:
    + Standards-Version: 3.8.0 (No changes required)
    + debhelper (>= 7)
  * debian/rules: Removed sed command that changed shebangs

  [ Stefano Rivera ]
  * Python 2.7 transition: Remove python version restrictions.
  * Convert to dh_python2.
    - Install as a private module in /usr/share/gapti
  * Use minimal dh7 rules.
  * Use 3.0 (native) source format.
  * Bumped Standards-Version to 3.9.1:
    - Point to versioned common-licence (GPL-3).
  * debian/control:
    - Depend on software-properties-gtk.
    - Add Homepage.

However, it still doesn't work, as software-properties-gtk has had some API changes:

Traceback (most recent call last):
  File "/usr/bin/gapti", line 12, in <module>
    import utils
  File "/usr/share/gapti/gapti/utils.py", line 6, in <module>
    from softwareproperties.gtk.DialogAptKey import DialogAddKey as apt_key
ImportError: No module named DialogAptKey

So my proposed branch is incomplete, and further work is required, or gapti should be removed from Ubuntu.
