突然我的 Ubuntu 停止播放视频。当我打开视频时，播放器建议我安装 gstreamer1.0-libav。但是，安装失败。
我尝试手动安装它，这是错误消息：
$ sudo apt-get install gstreamer1.0-libav

答案1
我的天啊。
$ sudo apt-get install libopus0
Suggested packages:
opus-tools
The following packages will be REMOVED:
gstreamer1.0-libav:i386 libavcodec54:i386 libavformat54:i386 libopus0:i386
The following NEW packages will be installed:
libopus0
$ sudo apt-get install gstreamer1.0-libav
The following NEW packages will be installed:
gstreamer1.0-libav libavcodec54 libavformat54
0 upgraded, 3 newly installed, 0 to remove and 18 not upgraded
现在它可以工作了...不知道为什么...但我很高兴。

我认为这是一个已知的问题Multi-Architecture包管理。apt-get提出了首选解决方案来保留当前安装的相同包的 arch，但在某些情况下这不是您想要的。
在这种情况下，最好的解决方案是将它们:i386（依赖树中的 libavcodec54 或 libavcodec-extra-54、libavformat54 等包）替换为相应的:amd64包。
据我所知，最简单的解决方案是使用aptitude提供所有其他可能的解决方案并让您选择您喜欢的解决方案。
在 VirtualBox（Ubuntu 14.04）上测试。我安装了：
sudo apt-get install gstreamer1.0-libav:i386 libavcodec54:i386 libavformat54:i386 \
libopus0:i386
尝试安装 gstreamer1.0-libav 会出现相同的错误消息：
# apt-get install gstreamer1.0-libav

解决此类情况的说明：
安装能力：
sudo apt-get install aptitude运行：
sudo aptitude按下并/搜索
gstreamer1.0-libavEnter检查是否不是
gstreamer1.0-libav:i368，用来n搜索下一个。然后按下+标记以进行安装
在这种情况下有两种解决方案，请参见底部的红色消息。使用.或,选择建议删除 4 条这正是我们要找的。
为了确认它是正确的解决方案，请按下，e这样它就会检查并显示它将要做什么。
如果可以，请按!“应用该解决方案”然后g开始安装过程。

答案3
我仍然收到相同的消息，但我稍微改变了@Sergey 的步骤并且对我有用
首先手动卸载以下软件包：
sudo apt-get remove gstreamer1.0-libav:i386 sudo apt-get remove libavcodec54:i386 sudo apt-get remove libavformat54:i386 sudo apt-get remove libopus0:i386现在安装：
sudo apt-get install libopus0 sudo apt-get install gstreamer1.0-libav
