Package dependencies cannot be resolved

This error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time.

The following packages have unmet dependencies:

emma: Depends: python:any (>= 2.7.5-5~) but it is a virtual package
      Depends: python-mysqldb (>= 1.2.1-p2-2) but it is not going to be installed
      Depends: python-gtk2 (>= 2.8.6-1) but 2.24.0-3ubuntu3 is to be installed
      Depends: python-glade2 (>= 2.8.6-1) but 2.24.0-3ubuntu3 is to be installed
