1、打开win下的 ：  启动或关闭windows功能，选中适用于linux的windows子系统，之后重启

2、打开 微软应用商店，搜linux，选ubuntu18.04LTS，之后获取，安装完成后打开

3、换源

先备份原来的

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

查看自己ubuntu的版本，Ubuntu 18.04 LTS 的代号是 ：bionic，之后编辑文件

lsb_release -c

sudo vim /etc/apt/sources.list

之后将原来的源替换为以下：

deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
