       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.

Я пытался следовать всем инструкциям из здесь , и это до сих пор не помогло мне.

В чем проблема и как ее исправить?

Редактировать:
Моя проблема заключается в том, что я не могу установить кодеки видео-плагина Gstreamer ffmpeg воспроизводить файлы .mpeg, .divx, .mpeg4, .ac3, .wmv и .asf
