Comment 10 for bug 857539

Hi, everybody!

> 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
