linux 软件源与依赖的问题

有些64位软件，需要32位库。比如ia32-libs，不小心卸载掉，永中office 等程序不能使用。重新安装ia32-libs时出现依赖问题：

sudo apt-get install ia32-libs

The following packages have unmet dependencies.
ia32-libs : Depends: ia32-libs-multiarch

需要更多的依赖

sudo apt-get install ia32-libs-multiarch

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 resolve the situation:

The following packages have unmet dependencies:
 ia32-libs-multiarch:i386 : Depends: gstreamer0.10-plugins-base:i386 but it is not going to be installed
                            Depends: gstreamer0.10-plugins-good:i386 but it is not going to be installed
                            Depends: gstreamer0.10-fluendo-mp3:i386

换163的源后问题解决
