/etc/apt/sources.list文件的Ubuntu资源的网站路径换乘国内的镜像源路径 - 国内的镜像源
清华：https://mirrors.tuna.tsinghua.edu.cn/
阿里云：http://mirrors.aliyun.com/pypi/simple/

- 修改前请备份一下：
sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup - 以阿里云为例，代码
sudo sed -i 's#http://archive.ubuntu.com/ubuntu/#http://mirrors.aliyun.com/ubuntu/#' /etc/apt/sources.list
sudo sed -i 's#http://security.ubuntu.com/ubuntu/#http://mirrors.aliyun.com/ubuntu/#' /etc/apt/sources.list

sudo apt update && sudo apt upgrade -y
