package libpurple-bin 1:2.10.9-0ubuntu3.4 failed to install/upgrade: package libpurple-bin is already installed and configured

I try to install Transmaggedon, and gstreamer. There was a package named gstreamer ffmpeg. I choose to install. The installation began, but that stop because there is no more package gstreamer for ffmpeg.
