Comment 5 for bug 226292

As a temporary workaround, https://launchpad.net/~schooltool-owners/+archive has zodb-3.8.0 and all it's associated dependencies.

Add to /etc/apt/sources.list:

deb http://ppa.launchpad.net/schooltool-owners/ubuntu hardy main
deb-src http://ppa.launchpad.net/schooltool-owners/ubuntu hardy main

Then:

apt-get install python-zodb
apt-get install python-zope.interface
(will uninstall python-zopeinterface, presumably the older version of the same package)
