Unable to evolve timetables

This bug prevents me from using my database at all. Would it be possible to get the patch asap. I would be glad to help by checking it out on my system.

When you upgraded a backup Data.fs should have been put in /var/lib/schooltool

So in the short run you should be able to downgrade your packages back to the version in universe and copy the backup to Data.fs.

Might need a better explanation from Gediminas...

The fix is in the branch lp:~schooltool-owners/schooltool/flourish

Check it out, then

  $ make instance
  $ cp /var/lib/schooltool/Data.fs instance/var/
  $ make run

evolution should now work, and the instance run.

You can then copy the evolved Data.fs back to its place.

Thank you for quick responding.

I've found the branch "schooltool-owners/schooltool/flourish". But which
revision is it? Could you please give me some more detailed hint, what I have
to do?

Thank you very much for your help - and for schooltool at all (I use it every
day).

You just need to check out the current branch, so, a bit more explicitly...

Install bzr if you haven't: "sudo apt-get install bzr"
Then: "bzr branch lp:~schooltool-owners/schooltool/flourish"

That'll check out the code and put it in a directory named "flourish." You can then cd into that directory and do the remaining ("make...") steps above.

I wonder why have you encountered this error if you "use schooltool every day".

"flourish" series is in development still, so you would be installing this version only if you want to help us test that the new user interface. It is usable, but we are still fixing important bugs like this one.

Everyone isn't as disciplined a systems administrator as you Gediminas. ;-)

Some days ago I upgraded to Ubuntu 11.10. After the upgrade schooltool didn't
start up anymore, because of the failing evolving. That's why I installed what
I thought of being the actual version (1.9.1). There are some days left,
because we have still autumn vacations here. But in the next week I will need
it badly again.

So which is the production version for "Oneiric ocelot"? Where should I get
the packages?

I did the compiling as you pointed me to, but the instance could not be
evolved (output see below).

Thank you very much for your support.

OK. The official version of schooltool is already in Ubuntu since 11.04 . You do not need to use the SchoolTool PPA anymore, although there will be updates in there.

Until yesterday, there were 1.9.* packages in the ppa for oneiric. Now the "flourish" packages are in a separate PPA, https://launchpad.net/~schooltool-owners/+archive/dev , so that accidents like yours won't happen.

The last version in Ubuntu is 1.7.0 and that's what you should be upgrading to on production system.

To revert to Oneiric packages, do:

$ sudo apt-get install schooltool/oneiric python-schooltool/oneiric python-schooltool.gradebook/oneiric python-schooltool.intervention/oneiric python-schooltool.lyceum.journal/oneiric

Done. But ist doesn't start. Maybe this is another bug at all? Could you
please have a look at the logfiles below?

Thank you and best regards
