I'm trying to install a program by Cisco called Packet Tracer ver 3.0. I am having issues installing it.

The file is a .deb. When I install it with dpkg -i I receive a message saying that the dependency qt-at-spi is missing.

I run "apt-get install qt-at-spi" and get the message "E: Can't select candidate version from package qt-at-spi as it has no candidate"

Any suggestion on how to install this?
