我想在 64 位 ubuntu 上安装 32 位 qt 库，但是 apt-get 无法解析依赖项。
首先我跑：
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
然后我重新启动并运行：
sudo apt-get install qtdeclarative-dev:i386
我得到了：

The following information may help to resolve the situation:

Depends: libcheese7 (>= 3.0.1) but it is not going to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
这在 Ubuntu 64 位 14.04.2 上运行良好，但现在看来 Qt 还没有跟上 HWE 堆栈的变化？
还有谁遇到过这个问题并知道如何解决吗？

答案1
我可以通过手动安装 libgl1-mesa-dri:i386，然后安装 qtdeclarative5-dev:i386 来解决这个问题。我不确定为什么 apt-get 无法解决这个依赖关系。
sudo apt-get install libgl1-mesa-dri:i386
进而：
sudo apt-get install qtdeclarative5-dev:i386
