Debian:未满足的依赖关系

Question

只是试图在Debian上安装xfce4，但我得到了未满足的依赖关系错误：

root@iPig:~# apt-get install xfce4
Reading package lists... Done
Building dependency tree       
Reading state information... Done
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 to resolve the situation:

The following packages have unmet dependencies:
 xfce4 : Depends: xfce4-panel (>= 4.10.0) but it is not going to be installed
         Depends: gtk2-engines-xfce (>= 3.0.0) but it is not going to be installed
         Depends: xfce4-mixer (>= 4.10.0) but it is not going to be installed
         Depends: orage (>= 4.8.0) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

我在谷歌上搜索了很多，却找不到任何有用的提示。知道怎么解决这个问题吗？如果您需要更多信息，请告诉我。

运行智能，这是输出
