有人安装了 ubuntu-restricted-extras 吗？（例如，您需要它来编码 mp3）。当我尝试安装它时，它要删除以下软件包：
# aptitude install ubuntu-restricted-extras

有些软件包看起来并不那么不重要，所以我对接受这个解决方案有些怀疑。到目前为止，有人安装过这些软件包，并且没有遇到任何问题吗？
答案1
在我看来，这似乎非常非常错误。
sudo apt-get install ubuntu-restricted-extras
告诉我......
正在读取软件包列表...完成 构建依赖关系树 正在读取状态信息...完成 将会安装以下额外的软件包： gstreamer0.10-插件-坏-多重宇宙 libavcodec-extra-53 libavutil-extra-51 libfaac0 libmjpegtools-1.9 libopenjpeg2 libquicktime2 建议的软件包： libfaad0 下列软件包将被删除： libavcodec53 libavutil51 将会安装以下新软件包： gstreamer0.10-插件-坏-多重宇宙 libavcodec-extra-53 libavutil-extra-51 libfaac0 libmjpegtools-1.9 libopenjpeg2 libquicktime2 ubuntu 受限附加功能 0 个升级，8 个新安装，2 个删除，0 个未升级。 需要获取 6,733 kB 的档案。 此操作后，将使用2,217 kB的额外磁盘空间。 您想继续 [Y/n] 吗？
这看起来更像是正确数量的包裹。
这是您首先需要修复的部分：
The following packages have unmet dependencies:
libavutil-extra-51 : Conflicts: libavutil51 but 4:0.8.1-0ubuntu1 is installed.
libavcodec-extra-53 : Conflicts: libavcodec53 but 4:0.8.1-0ubuntu1 is installed.
这些包将会从列表中消失。
答案2
想补充一点，您可以考虑n在询问解决方案时按下，然后会显示其他可能的解决方案。有时最佳选项不是第一个。我甚至觉得 aptitude 显示建议的方式很方便。您可以按下?以查看所有可能的命令，例如：
n: reject the proposed changes and search for another solution
.: move to the next solution
,: move to the previous solution
