Ubuntu Server LTS 20.04 安装桌面
Ubuntu server版安装后没有图形界面，为了管理方便，安装完成后，即可安装界面和远程桌面工具。
1、更新源nano /etc/apt/sources.list在sources.list中加入以下代码：
# 清华源# 注释源码镜像以提高更新速度 deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multivers # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse
然后在命令行运行以下命令更新apt-get updateapt-get upgrade
2、安装桌面apt-get install -y ubuntu-desktop
3、安装xrdpapt-get install -y xrdp安装完成后，即可使用Windows远程桌面工具登录Ubuntu。
