If you installed Zenmap in another directory, you may have to add the
modules directory to the PYTHONPATH environment variable.
i know it needs to install gtk but when i download gtk and try to install it with dpkg i get this error:
dpkg: dependency problems prevent configuration of python-gtk2:
python-gtk2 depends on python-cairo (>= 1.0.2-1.1); however:
Package python-cairo is not installed.
python-gtk2 depends on python-gobject-2 (>= 2.21.3); however:
