Comment 2 for bug 273314

Attempting to overcome pidgin partial install issue, using Synaptic, receive "Could not mark all packages for installation or upgrade. The following packages have unresolved dependencies. Make sure that all required repositories are added and enabled in the preferences."
In the error screen it lists:

pidgin:
 Depends: libpurple0 but it is not going to be installed
 Depends: pidgin-data (<1:2.5.0-z) but 1:2.5.2-0ubuntu1~hardy1 is to be installed
