Linux上下载大的点的软件都把人等的崩溃。都是从国外的网站下载，在我大天朝你们懂的，所以就把他的源给换一下，我觉得还是阿里牛逼！！！！多谢马粑粑了！

首先我需要搞清楚是哪个发行版的Linux的第几个版本，对应版本去找源

我本次在虚拟机上装的是ubuntu20.04TLS

阿里云ubuntu源路径，根据版本去查找对应的
https://developer.aliyun.com/mirror/ubuntu

备份原始文件

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

sudo su获得超级管理员权限
编辑sources.list，删除之前的链接，将阿里云的链接粘贴进去，保存

vim /etc/apt/sources.list
更新源（前面已经获得超级管理员权限）

apt-get update
apt-get update

好了，完成。现在下载杠杠的！
