AssertionError

An assert in evolution script is nasty, because if it is hit, application cannot start. But this is a case that "we do not handle", although I don't know how that could happen.

This code in was added to gradebook after 0.9.0 (post-Natty)

Maybe schooltool.gradebook.generations.evolve1 has not run? But this would be a very old schooltool (1.2 or earlier)

Ikpeer: you can try installing an earlier version of gradebook. Get it from
http://packages.ubuntu.com/natty/python-schooltool.gradebook

and install with

$ sudo dpkg --install python-schooltool.gradebook_0.9.0-0ubuntu1_all.deb

SchoolTool should now start without this error.

Then, you can upgrade gradebook again to the version from oneiric. Maybe this time evolution will succeed.

This has worked very well. I can use the database again - which is quite important for me. Thank you very, very much!

Before the upgrade to Oneiric I used Natty with the package Schooltool-2009 (Schooltool 1.6?). I started the usual upgrade and after this schooltool didn't start up anymore.

Nevertheless I am ready to test new versions - if only I have a functional production version ready.

Thank you for your work on schooltool.

I have tried to resolve this in http://bazaar.launchpad.net/~schooltool-owners/schooltool.gradebook/flourish/revision/381

released as 1.9.2

Not sure if this change solves the problem, or it was enough to run an older version first, but marking this as fixed.
