我正在尝试在我的 64 位系统（基于 Ubuntu 12.10）上安装 32 位 gstreamer 插件。我可以安装软件包 gstreamer0.10-plugins-base:i386 和 gstreamer0.10-plugins-good:i386。但是，gstreamer0.10-plugins-bad:i386、gstreamer0.10-plugins-bad-multiverse:i386 和 gstreamer0.10-plugins-ugly:i386 与我系统上已安装的 64 位软件包冲突：
$ sudo apt-get install gstreamer0.10-plugins-bad:i386

这意味着我无法在使用 gstreamer 的 32 位应用程序中播放 mp3（以及其他内容）。有办法解决这个问题吗？
答案1
apt 拒绝安装的库（例如libdvdread4）尚未实现多架构。因此，它们无法同时安装同一库的amd64和版本。i386
除了帮助我们多架构更多库之外，你能做的并不多。
