Ubuntu 12.10 损坏

我已安装并运行 ubuntu 12.10。但不知何故我却把一切都搞砸了。现在，我看不到登录屏幕。它一直显示黑屏，光标在“Jupiter 健康检查”处闪烁。

按下任意键，我就能进入终端。

我尝试过这个：

 sudo apt-get install ubuntu-desktop

输出为：

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:
 ubuntu-desktop : Depends: nautilus but it is not going to be installed
                  Depends: nautilus-sendto but it is not going to be installed
                  Recommends: brasero but it is not going to be installed
                  Recommends: nautilus-share but it is not going to be installed
                  Recommends: transmission-gtk but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

我怎样才能继续？

似乎您已禁用某些存储库。首先，让我们使用以下命令重新启用它们：

 sudo software-properties-gtk -e universe multiverse restricted

之后，安装ubuntu-desktop：

 sudo apt-get update && sudo apt-get install ubuntu-desktop

笔记

如果尚未software-properties-gtk安装，请使用：命令进行安装
sudo apt-get install software-properties-gtk
。
