我正在尝试使用此命令在我的 ubuntu 桌面 14.04 上安装 ubuntu-sdk
sudo apt-get install ubuntu-sdk
但是我收到此错误“无法安装某些软件包”。这可能意味着您请求了一个不可能的情况，或者如果您使用的是不稳定的发行版，则某些必需的软件包尚未创建或已从传入中移出。以下信息可能有助于解决这种情况：
The following packages have unmet dependencies:
libcheese-gtk23 : Depends: libclutter-gtk-1.0-0 (>= 0.91.8) but it is not going to be installed
Depends: libcogl15 (>= 1.15.8) but it is not going to be installed

E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
我跑
sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade
但没有运气，请帮忙。
