Schooltool doesn't start after upgrade to 12.04

While playing around I cannot reproduce the assertion error. By the way: How can I determine, which generation my database has?

Instead I get an Attribute Error. This is what paste.log says:

You can see what generations the database has at http://localhost:7080/control/generations.html

And the last error means that gradebook plugin is not available. But schooltool starts I think?

This error is being fixed by schooltool.requirement generation 1 but that fails as seen by your first error. I think it was reported already :(

I think you can edit /usr/lib/python2.7/dist-packages/schooltool/requirement/generations/evolve1.py and remove the line 48 (assert). The evolution will then succeed.

The server starts without problems when I remove my database.

After this I removed the schooltool packages and reinstalled them again. Then I stopped the server and replaced the new database with my original.

The server fails again with the assertion error. "paste.log" says:

It has worked!!! Thank you very much! My database is up and running!

Since my old database is now evolved I hope future updates will work as
expected.

Thanks again and best regards! Keep on with this software!

I thought this was fixed as Bug #882656, but apparently not.

Removed assert, it works even when the condition is not true.
