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.
I have tried to follow every instruction from here and it has still not helped me.
What is the problem and how do I fix it ?
Edit:
My problem is that I can't install Gstreamer ffmpeg video plug-in
codecs to play .mpeg, .divx, .mpeg4, .ac3, .wmv and .asf files
sudo apt-get update
first, and then see if you still get this error. – ish Aug 18 '12 at 16:18
