媒体播放器的未满足依赖关系
我安装了Ubuntu 12.04，而它处于beta2阶段。 从那时起，我一直在接受常规和部分升级（我不明白为什么我提供此选项虽然我在最新的Ubuntu版本上）选项。 我无法使用原生的“电影播放器”播放像MP4这样的格式。 每次我尝试播放这样的格式时，电影播放器用于搜索插件，最后用于给我这个结果：以下软件包有未满足的依赖项：

vlc : Depends: vlc-nox (= 2.0.1+git20120502+r198-0~r36~precise1) but it is not going to be installed Depends: libvlccore5 (>= 2.0.0) but it is not going to be installed Recommends: vlc-plugin-notify (= 2.0.1+git20120502+r198-0~r36~precise1) but it is not going to be installed Recommends: vlc-plugin-pulse (= 2.0.1+git20120502+r198-0~r36~precise1) but it is not going to be installed E: Unable to correct problems, you have held broken packages.
我使用ppa:videolan/stable-daily PPA。
我该如何解决这个问题？
您获得部分升级选项的原因是因为您使用的是第三方PPA，并且它引入了无法满足的依赖性问题。
你有几个选择。
- 删除videolan / stable-daily PPA并从官方回购中安装VLC
- 联系该PPA的所有者，当他们的PPA包含git20120503版本时，询问他们为什么取决于git20120502版本（您可能还会尝试再次安装VLC，因为它可能是已经解决的打包问题）
- 找到vlc-nox和libvlccore5的正确版本，并通过dpkg手动安装它们。
