系统设置停止显示

在我的硬盘驱动器与Ubuntu 14.04.1放在一个新的电脑系统后,设置将不会显示。 我试过了:

sudo apt-get install unity-control-center 

但我明白了

 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: 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 edgers获得的mesa包有关,我已经注意到了

  • unity-control-center取决于libcheese7
  • libcheese7依赖于gstreamer1.0-clutter
  • gstreamer1.0-clutter取决于libcogl15
  • libcogl15 dependslibegl1-mesa-drivers
  • libegl1-mesa-drivers取决于libegl1-mesa-drivers
  • libegl1-mesa-drivers取决于libglapi-mesa ( = 10.1.3-0ubuntu0.3 )

我安装了:

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

我尝试过安装它:

 sudo apt-get install libglapi-mesa=10.1.3-0ubuntu0.3 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: indicator-bluetooth : Depends: unity-control-center but it is not going to be installed or gnome-control-center but it is not going to be installed or ubuntu-system-settings but it is not going to be installed libcheese7 : Depends: libclutter-gst-2.0-0 (>= 0.10.0) but it is not going to be installed Depends: gstreamer1.0-clutter but it is not going to be installed libclutter-gtk-1.0-0 : Depends: libclutter-1.0-0 (>= 1.13.10) but it is not going to be installed Depends: libcogl15 (>= 1.15.8) but it is not going to be installed libcogl-pango15 : 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. 

我已经禁用了PPA

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

所以问题在于依赖关系,即

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

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的所有软件包,系统设置对话框打开了:)

这里有一个错误报告。 (解决方案来自#10回复)

显然我的问题通过输入以下行解决了:

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

尝试使用sudo apt-get install -f unity-control-center或搜索缺少的软件包名称并手动安装。
