Ubuntu 14.04，安装gstreamer1.0-libav时出现问题，unmet依赖项
突然，我的Ubuntu停止播放video了。 当我打开video时，播放器建议我安装gstreamer1.0-libav 。 但是，它无法安装。
我尝试手动安装它，这是错误消息：
$ sudo apt-get install gstreamer1.0-libav Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: gstreamer1.0-libav : Depends: libavcodec54 (>= 6:9.1-1) but it is not going to be installed or libavcodec-extra-54 (>= 6:9.13) but it is not going to be installed Depends: libavformat54 (>= 6:9.1-1) but it is not going to be installed E: Unable to correct problems, you have held broken packages.
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
现在它有效……不知道为什么……但我很高兴。
我认为在处理Multi-Architecture包管理时这是一个已知问题。 apt-get提出了首选解决方案，以保持当前安装的相同软件包的拱门，这在某些情况下并不是您想要的。
在这种情况下，最好的解决方案是用相应的:amd64包替换那些:i386 （libavcodec54或libavcodec-extra-54，libavformat54，..来自依赖树的其他包）。
AFAIK，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，让您选择您喜欢的。
在VirtualBox上测试（Ubuntu 14.04）。 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会引发相同的错误消息：
# apt-get install gstreamer1.0-libav Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: gstreamer1.0-libav : Depends: libavcodec54 (>= 6:9.1-1) but it is not going to be installed or libavcodec-extra-54 (>= 6:9.13) but it is not going to be installed Depends: libavformat54 (>= 6:9.1-1) but it is not going to be installed E: Unable to correct problems, you have held broken packages.
解决此类案件的说明：
-
安装aptitude：
sudo apt-get install aptitude -
运行：
sudo aptitude -
按/并搜索
gstreamer1.0-libav然后按Enter键检查它不是
gstreamer1.0-libav:i368，使用n搜索下一个。 -
然后按+标记它以进行安装
-
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。 或者，选择建议4删除 ，这是我们正在寻找的。
-
要确认它是正确的解决方案，请按e以便它将检查并显示它将要执行的操作。

如果没问题，请按！ 应用该解决方案然后g开始安装过程。

我仍然收到相同的消息，但我稍微改变了@Sergey的步骤，并为我工作

首先手动卸载以下包：
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
