Some packages could not be installed. This may mean that you have  
requested an impossible situation or if you are using the unstable

The following information may help to resolve the situation:  

The following packages have unmet dependencies:

按照规定，我将 设置PATH为 include /opt/qt5/bin。我想知道这个问题是否有人熟悉。非常感谢您的时间。

Answer 1

今天我现有的安装也开始发生这种情况。我的猜测是 Canonical 正在更改包依赖项，要么为最终的 Qt5 版本做准备，要么修改 Qt5 beta。

请密切关注http://developer.ubuntu.com/get-started/gomobile/ppa:canonical-qt5-edgers/qt5-beta1以及ppa:canonical-qt5-edgers/qt5-proper更新的说明

编辑：昨天的构建日志表明'deb http://ppa.launchpad.net/canonical-qt5-edgers/qt5-proper/ubuntu quantal main'现在正在使用。

我想我们只需要等待更新的说明。

我遇到了同样的问题，并在 #ubuntu-phone irc 寻求帮助。他们提出了从启动板使用ppa:canonical-qt5-edgers/qt5-properPPA 的解决方案。因此，只需将https://launchpad.net/~canonical-qt5-edgers/+archive/qt5-proper添加到sources.list. 之后运行

    sudo apt-get update 

您应该能够完成http://developer.ubuntu.com/get-started/gomobile/中的说明。
