收到“服务器意外关闭网络连接”

我使用 Jclouds API 创建了虚拟机，并在 Putty 登录中提供了公共地址。我尝试通过以下命令在虚拟机中安装 GUI

sudo apt-get install ubuntu-desktop

它已安装，但在重新启动 Ubuntu 服务器时我失去了互联网连接并收到如下消息：

sudo reboot

Server unexpectedly closed network connection

那么服务器将不会响应。

在您的服务器上尝试以下 GUI：

KDE Plasma 桌面：sudo apt-get install kde-plasma-desktop

XFCE4：sudo apt-get install xfce4

远程桌面连接工具：sudo apt-get install lxde

GNOME 3：sudo apt-get install gdm

       sudo add-apt-repository ppa:gnome3-team/gnome3-next 

       sudo add-apt-repository ppa:gnome3-team/gnome3-staging

进而sudo apt-get update

sudo apt-get dist-update

sudo apt-get install gnome-shell

这些将为您安装一个原始 GUI，即 GUI，没有任何附带应用程序，例如 KDE Plasma Desktop 中的 Amarok 和 Muon。
