Ubuntu 12.04中未满足的依赖项？
The following packages have unmet dependencies: gstreamer0.10-ffmpeg: Depends: libavcodec-extra-53 (>= 4:0.7-1) but 4:0.7.2.1ubuntu2 is to be installed Depends: libavformat-extra-53 (>= 4:0.7-1) but 4:0.7.2.1ubuntu2 is to be installed Depends: libavutil-extra-51 (>= 4:0.7-1) but 4:0.7.2.1ubuntu2 is to be installed Depends: libc6 (>= 2.7) but 2.15-0ubuntu10 is to be installed Depends: libglib2.0-0 (>= 2.24.0) but 2.32.3-0ubuntu1 is to be installed Depends: libgstreamer-plugins-base0.10-0 (>= 0.10.31) but 0.10.36-1ubuntu0.1 is to be installed Depends: libgstreamer0.10-0 (>= 0.10.31) but 0.10.36-1ubuntu1 is to be installed Depends: liborc-0.4-0 (>= 1:0.4.14) but 1:0.4.16-1ubuntu2 is to be installed Depends: libpostproc-extra-52 (>= 4:0.7-1) but 4:0.7.2.1ubuntu2 is to be installed Depends: libswscale-extra-2 (>= 4:0.7-1) but 4:0.7.2.1ubuntu2 is to be installed gstreamer0.10-ffmpeg:i386: Depends: libavcodec-extra-53 (>= 4:0.7-1) but 4:0.7.2.1ubuntu2 is to be installed Depends: libavformat-extra-53 (>= 4:0.7-1) but 4:0.7.2.1ubuntu2 is to be installed Depends: libavutil-extra-51 (>= 4:0.7-1) but 4:0.7.2.1ubuntu2 is to be installed Depends: libc6 (>= 2.7) but 2.15-0ubuntu10 is to be installed Depends: libglib2.0-0 (>= 2.24.0) but 2.32.3-0ubuntu1 is to be installed Depends: libgstreamer-plugins-base0.10-0 (>= 0.10.31) but 0.10.36-1ubuntu0.1 is to be installed Depends: libgstreamer0.10-0 (>= 0.10.31) but 0.10.36-1ubuntu1 is to be installed Depends: liborc-0.4-0 (>= 1:0.4.14) but 1:0.4.16-1ubuntu2 is to be installed Depends: libpostproc-extra-52 (>= 4:0.7-1) but 4:0.7.2.1ubuntu2 is to be installed Depends: libswscale-extra-2 (>= 4:0.7-1) but 4:0.7.2.1ubuntu2 is to be installed 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. 我试图遵循这里的每一条指令，它仍然没有帮助我。
有什么问题，我该如何解决？
编辑：
我的问题是我无法安装Gstreamer ffmpegvideo插件编解码器来播放.mpeg，.divx，.mpeg4，.ac3，.wmv和.asf文件
您似乎使用了非常过时的库，例如“libavcodec-extra-53（> = 4：0.7-1），但是要安装4：0.7.2.1ubuntu2 ”。 该版本于2011年12月26日在12.04 dev发布，并已多次被取代。
目前的12.04版本是4：0.8.3ubuntu0.12.04.1）精确安全
所以打开软件源， software-properties-gtk并确保在Ubuntu Software下检查第1个，并在Updates第1个。 检查2
然后更新您的来源并查看
