系统设置停止显示

Question

当我把我的硬盘与Ubuntu14.04.1放在一个新的pc系统设置将不会出现。我试过：

sudo apt-get install unity-control-center

但我明白

Reading package lists... 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

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 unity-control-center : Depends: libcheese-gtk23 (>= 3.4.0) but it is not going to be installed
                        Depends: libcheese7 (>= 3.0.1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

我能做什么?

编辑

这个问题可能与我从xorg编辑获得的mesa软件包有关，我注意到

• unity-control-center依赖于libcheese7
• libcheese7依赖于gstreamer1.0-clutter
• gstreamer1.0-clutter依赖于libcogl15
• libcogl15 depends on libegl1-mesa-drivers
• libegl1-mesa-drivers依赖于libegl1-mesa-drivers
• libegl1-mesa-drivers依赖于libglapi-mesa ( = 10.1.3-0ubuntu0.3 )

我安装了：

libglapi-mesa 10.5.0~git20150105.21a280f8-0ubuntu0ricotz~trusty来自xorg-edgers PPA.

我试过用以下方式安装：

sudo apt-get install libglapi-mesa=10.1.3-0ubuntu0.3

我的PPA已经被

sudo ppa-purge  ppa:xorg-edgers/ppa && sudo apt-get update

Answer 1

因此，问题在于依赖关系，即

libegl1-mesa-drivers依赖于libglapi-mesa ( = 10.1.3-0ubuntu0.3 ) (也许应该是>=)

我再次添加了xorg-edgers PPA，然后适当地降低了ppa的级别，如下所示：

sudo add-apt-repository ppa:xorg-edgers/ppa && sudo apt-get update
sudo ppa-purge  ppa:xorg-edgers/ppa && sudo apt-get update

现在，我删除了xorg-edgers中的所有包，打开了系统设置对话框:)

Answer 2

这个这里有一个错误报告。(答案来自10号回复)

显然，我的问题是通过输入以下一行来解决的：

sudo apt-get install libglew-dev libcheese7 libcheese-gtk23 libclutter-gst-2.0-0 libcogl15 libclutter-gtk-1.0-0 libclutter-1.0-0

Answer 3

尝试执行sudo apt-get install -f unity-control-center或搜索缺少的包名，然后手动安装它们。
