education-chemistry: fails to install: err 67: Custom distribution education does not exist

[Gordon Stevens]

Same bug in Debian: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=465608

err 67: Custom distribution education does not exist
dpkg: error while cleaning up:
 subprocess post-removal script returned error exit status 67
Errors were encountered while processing:
 /var/cache/apt/archives/education-chemistry_0.824ubuntu2_i386.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

- apt gave error also on first install attempt; now appears each time apt is used.
==========

Stems from an issue with cdd-dev. From the debian-edu 0.826 changelog:
* Build-Depends: cdd-dev (>= 0.4.7)
  Reason: The change in cdd to enable builds of Arch any for some CDDs
  leaded to the error that postinst/postrm files now contained two copies
  of the same code. This is fixed in cdd-dev 0.4.7 and thus debian-edu
  has to be rebuilded.

Diff between cdd 0.4.4 and 0.4.7 (as pulled from snapshot.debian.net) is attached.

====TEST CASE====

With a base install of Hardy attempt to install the package "education-chemistry"

[Greg Grossmeier (greg.grossmeier)]

Hardy has education-chemistry version 0.822 and the fix was in 0.826 (according to the Debian bug report you referenced).

Intrepid has 0.835 so it shouldn't be a problem there. Marking as Fix Released (available in development).

If you test it in Intrepid and it is still a problem please reopen this bug.

[Greg Grossmeier (greg.grossmeier)]

Propose to provide a fix for the Hardy version via a Stable Release Update.

Looking at the attachments in this bug report, I noticed that "cdd_0.4.4_to_0.4.7.diff" was not flagged as a patch. A patch contains changes to an Ubuntu package that will resolve a bug and this attachment is one! Subsequently, I've checked the patch flag for it. In the future when submitting patches please use the patch checkbox as there are some Launchpad searches that use this feature. Thanks for your contribution Greg Grossmeier!
