Linux 未满足的依赖关系？有破损的包裹吗？

我正在尝试建立并运行一个vpn，并通过shrew软客户端来实现。当我运行命令时：

sudo apt-get install libqt4-core libqt4-dev libqt4-gui qt4-dev-tools

我得到以下输出流：

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

The following information may help to resolve the situation:

我在网上搜索过，但没有结果。我已经运行了apt get-f install和dpkg--configure-a，但仍然无法安装。我甚至用greed保存包，但没有输出。你有什么想法告诉我为什么或者给我指出正确的方向吗？我在chromebook上的chrooted 12.04精确，如果这很重要的话。
