统一控制中心自行卸载

Question

我不知道它是如何卸载的，因为我以前有过它，但是当我再次安装它时，我会得到以下错误：

oierlauzi@akerbeltz:~$ sudo apt-get install unity-control-center
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.

我读过几个答案，但没有一个能解决我的问题。我也不能用天赋来解决这个问题。

Answer 1

当我升级到ubuntu14.04时，我遇到了很多像这样的严重错误。在更新过程中，许多软件源被停用，需要通过进入软件中心再次激活它们。编辑->软件资源->其他软件，并再次检查所有的来源.

Answer 2

您可以先尝试以下方法：

sudo apt-get -f install
sudo apt-get update
sudo apt-get upgrade

最后两行只是为了确保存储库和缓存以及没有错误。另一种方式是：

sudo apt-get --fix-missing install

另一种方法是实际安装它们所依赖的软件包。

sudo apt-get install libcheese-gtk23 libcheese7
sudo apt-get -f install`
