[Bug 1246539] Re: get-distro-upgrade.py needs to be converted to python3

[Craig Gowing (credativ)]

I got this error pop up around 4 times every login on Kubuntu 13.10
amd64 (upgraded), and then at random intervals after that.

Oddly on my other Kubuntu 13.10 amd64 box (again upgraded) this module is available for python 2.7:
>>> import packagekit.backend
>>> packagekit.backend
<module 'packagekit.backend' from '/usr/lib/python2.7/dist-packages/packagekit/backend.pyc'>

The py files on my working box were in /usr/share/pyshared/packagekit and symlinked to /usr/lib/python2.7/dist-packages/packagekit.
They must have come from some old package that was removed during the upgrade but preserved the files I guess?

I tested out two possible workarounds and they both seemed to work:

1. Modify /usr/share/PackageKit/helpers/aptcc/get-distro-upgrade.py and change the first line to:
#!/usr/bin/env python3

2. Copy over /usr/share/pyshared/packagekit/ from my working box and
symlink the py files to /usr/lib/python2.7/dist-packages/packagekit/
