SchoolTool server fails to start with an error:

it is my immediate priority to create schooltool (and all the dependencies, including zope) packages for karmic

[Gediminas Paulauskas (menesis)]

I have uploaded python-schooltool_2009.04.17-2 to https://edge.launchpad.net/~schooltool-owners/+archive/ppa/+build/1312575

You may need to manually resolve dependencies. Choose to upgrade python-schooltool and downgrade python-zope.component to version 3.4.0 from SchoolTool PPA.

Doing so would fix the exception posted in paste.log

Please try and reply if the server now starts, sudo /etc/init.d/schooltool-2009 start

So if you upgraded to karmic, you may have to downgrade some packages manually. Use SchoolTool PPA for jaunty, and downgrade the following packages:

zodb < 3.9.0
zope.component < 3.6.0
zope.i18n < 3.6.0
zope.location < 3.5.0
zope.publisher < 3.6.0
zope.security < 3.6.0
zope.traversing < 3.6.0

python-schooltool 1:1.0.3-2ubuntu2 package puts that into depends, upgrade it and then resolve other dependencies.

After doing so, your schooltool server should work on karmic, it does on my machine.

How does one actually do that?

[Gediminas Paulauskas (menesis)]

I solve all dependency problems using `aptitude`. With it you can choose, which solution to use when there is a conflict.

Or I think this would work:
  apt-get install python-schooltool python-zope.component/jaunty python-zodb/jaunty ...

You can pin packages to specific source in apt.conf, but I do not have an example now.

[Gediminas Paulauskas (menesis)]

This bug was fixed by:

python-schooltool (1:1.0.3-2ubuntu2) jaunty; urgency=low

 * Require versions compatible with SchoolTool 1.0 (Closes LP: #462254):
   - zope.i18n < 3.6.0
   - zope.location < 3.5.0
   - zope.publisher < 3.6.0
   - zope.security < 3.6.0
 * Restore a replace of PILwoTk with PIL in setup.py and requires.txt

All the packages are now in karmic PPA, but the dependencies cannot be automatically satisfied. To get schooltool installed and not be bothered by upgradable packages that would break schooltool, add this to /etc/apt/preferences ::

Explanation: prefer packages from SchoolTool PPA
Package: *
Pin: release o=LP-PPA-schooltool-owners
Pin-Priority: 1001

Instead of selecting all packages (*), you can pin only the conflicting packages, see the attached file.
