2.3. 更新源
sudo apt -y update
sudo apt -y upgrade

3，在Ubuntu Server 18.04系统上安装GNOME图形桌面环境
sudo apt -y install tasksel

3.1，执行tasksel
3.2，选择要安装的图形界面

选择Ubuntu桌面后，单击空格键将其选中，按Tab键选择Ok，然后按键盘上的Enter键。这将在Ubuntu Server上安装成功的GNOME桌面所需的一切。完成此过程后，重新启动服务器，重启后，LightDM显示欢迎您界面。
至此，您可以在这个服务器上使用方便的图形图像桌面了。

4，安装Anbox
Anbox 是 “Android in a box” 的缩写。Anbox 是一个基于容器的方法，可以在普通的 GNU/Linux 系统上启动完整的 Android 系统。

4.1，安装
Anbox 也可作为 snap 软件包安装，请确保你已经在你的系统上启用了 snap 支持。

Anbox 软件包最近被添加到 Ubuntu 18.10 (Cosmic) 和 Debian 10 (Buster) 软件仓库。如果你正在运行这些版本，那么你可以轻松地在官方发行版的软件包管理器的帮助下安装。否则可以用 snap 软件包安装。

为使 Anbox 工作，确保需要的内核模块已经安装在你的系统中。对于基于 Ubuntu 的用户，使用下面的 PPA 来安装它。
sudo add-apt-repository ppa:morphis/anbox-support
sudo apt -y update
sudo apt install linux-headers-generic anbox-modules-dkms
在你安装 anbox-modules-dkms 软件包后，你必须手动重新加载内核模块，或需要系统重新启动。
sudo modprobe ashmem_linux
sudo modprobe binder_linux
安装snap
sudo apt -y install snap
通过snap安装Anbox
sudo snap install --devmode --beta anbox
安装adb工具
sudo apt install android-tools-adb
adb工具简使用
adb devices
adb shell
adb tcpip
adb install/uninstall

5，最终效果图如下，可在Anbox中安装QQ，Wechat等。
