ubuntu 更换系统软件源 和 pip源

 一、 更换系统软件源

1、备份：

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

2、修改：

sudo gedit /etc/apt/sources.list 

# 阿里云源
deb http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse

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

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

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

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


# 清华大学源
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse
deb-src http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse

deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse
deb-src http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse

deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
deb-src http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse

deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse
deb-src http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse

deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-proposed main restricted universe multiverse
deb-src http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-proposed main restricted universe multiverse

3、生效：

sudo apt-get update

sudo apt-get upgrade

二、ubuntu更改pip源

1、家目录～下创建.pip文件夹

mkdir ~/.pip 

2、创建pip.conf文件

sudo gedit ~/.pip/pip.conf

3、将以下内容复制进pip.conf中

[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
index-index-url = https://mirrors.aliyun.com/pypi/simple/ 
[install]
trusted-host =
    pypi.tuna.tsinghua.edu.cn
    mirrors.aliyun.com

4、完成。

补充：国内可用的pip源

阿里云 [http://mirrors.aliyun.com/pypi/simple/]
 
中国科技大学 [https://pypi.mirrors.ustc.edu.cn/simple/]
 
豆瓣(douban) [http://pypi.douban.com/simple/]
 
清华大学 [https://pypi.tuna.tsinghua.edu.cn/simple/]
 
中国科学技术大学 [http://pypi.mirrors.ustc.edu.cn/simple/]
 
华中理工大学：[http://pypi.hustunique.com/]
 
山东理工大学：[http://pypi.sdutlinux.org/]

三 、windows下更改pip源

1、创建文件夹

        win+R 打开用户目录%HOMEPATH%，在此目录下创建 pip 文件夹，在 pip 目录下创建 pip.ini 文件

2、拷贝进以下内容

[global]
timeout = 6000
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
trusted-host = pypi.tuna.tsinghua.edu.cn
