After a fresh install, saying:
sudo apt-get install python-zodb
..did not properly set up ZODB. Some kind of version conflict/Ubuntu bug. Had to add following lines 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
..and say:
sudo apt-get install python-zodb sudo apt-get install python-zope.interface sudo apt-get install python-zope.proxy
See: https://bugs.launchpad.net/ubuntu/+source/zodb/+bug/226292/comments/5
