系统设置停止显示

Question

在我将装有 Ubuntu 14.04.1 的硬盘驱动器放入新电脑后，系统设置不会显示。我试过了：

sudo apt-get install unity-control-center

但我明白了

Reading package lists... Done

The following information may help to resolve the situation:

                        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

该问题可能与我从xorg edgers获得的 mesa 软件包有关，我注意到

• unity-control-center 取决于 libcheese7
• libcheese7 取决于 gstreamer1.0-clutter
• gstreamer1.0-clutter 取决于 libcogl15
• libcogl15 depends 在 libegl1-mesa-drivers
• libegl1-mesa-drivers 取决于 libegl1-mesa-drivers
• libegl1-mesa-drivers 取决于 libglapi-mesa ( = 10.1.3-0ubuntu0.3 )

我已经安装了：

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

我试过安装它：

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

我已经禁用了 PPA

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

Answer 1

所以问题出在依赖关系上，即

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

我再次添加了 xorg-edgers PPA，然后使用 ppa-purge 正确降级，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 中的所有软件包，并打开了系统设置对话框 :)

Answer 2

有此错误报告在这里。（解决方案来自#10回复）

显然我的问题是通过输入以下行解决的：

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