Comment 2 for bug 371630

Can you please tell us which Ubuntu release you are using? Jaunty?

Is the following folder created in your system?
/usr/share/python-support/python-paste

Did you try starting SchoolTool server manually from terminal?
The command is:
sudo /etc/init.d/schooltool-2009 start
See http://book.schooltool.org/htmlhelp/setup-initial.html

If you need to use SchoolTool very urgently and nothing helps, you can downgrade: make a back-up of your database, apt-get remove ST 2009, install 2008 again and use it with your data file.
