Ubuntu 13.04 登录时返回登录屏幕并更新问题

Question

为了解决这个问题，我卸载了 lightdm，现在 gdm 是默认设置。但我遇到了与 gdm 相同的问题。当我尝试重新安装 lighten 时，我收到：

您的 URL 中有错误/etc/apt/sources.list：

1. 跑步sudo nano /etc/apt/sources.list，

2. 查找文本

   http://us.archive.Ubuntu.com/ubuntu/ raring-updatea/main

   并将其替换为

   http://us.archive.Ubuntu.com/ubuntu/ raring-updates/main

3. 跑步

    sudo apt-get update
    sudo apt-get upgrade
