Comment 19 for bug 192992

I also ran into this, and accidentally reported it here since it didn't come up in a search for python-apt: https://bugs.launchpad.net/ubuntu/+source/python-apt/+bug/193076

My workaround is to install the python-apt_0.7.4ubuntu4_i386.deb package from here: https://launchpad.net/ubuntu/hardy/i386/python-apt/0.7.4ubuntu4

And pin it by creating a file called /etc/apt/preferences with the following 3 lines as contents:

Package: python-apt
Pin: release v=0.7.4ubuntu4
Pin-Priority: 1000
