Ubuntu22.04换源（自用）以及pip临时换源

转自两位，仅整合

Ubuntu 22.04换国内源 清华源 阿里源 中科大源 163源_ubuntu22阿里源_nudt_qxx的博客-优快云博客

ubuntu换镜像源（ubuntu换源）_乌班图镜像源_Fighting_1997的博客-优快云博客

#备份镜像源设置文件

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

#编辑镜像源设置文件

sudo gedit /etc/apt/sources.list

 清华源：

# 默认注释了源码镜像以提高 apt update 速度，如有需要可自行取消注释

pip

国内比较好的PyPI源库有：

    清华大学：https://pypi.tuna.tsinghua.edu.cn/simple
    阿里云：http://mirrors.aliyun.com/pypi/simple
    豆瓣：http://pypi.douban.com/simple

一、临时使用国内pypi镜像安装

比如安装 PyQt6,需要加镜像参数 ：

pip install PyQt6 -i http://pypi.douban.com/simple --trusted-host pypi.douban.com

pip install PyQt6 -i http://pypi.douban.com/simple --trusted-host pypi.douban.com
