近日需要使用pip3命令来测试jwt的安全性,但是始终无法安装pip3,某些包总是提示404错误。于是需要更新安装pip3的sudo命令中的镜像源。
推荐使用清华镜像:https://mirrors.tuna.tsinghua.edu.cn/help/ubuntu/
将下列文本添加到/etc/apt/sources.list文件里
# 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 deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ trusty main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ trusty main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ trusty-updates main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ trusty-updates main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ trusty-backports main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ trusty-backports main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ trusty-security main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ trusty-security main restricted universe multiverse # 预发布软件源,不建议启用 # deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ trusty-proposed main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ trusty-proposed main restricted universe multiverse
或者进入repogen.simplylinux.ch 选择合适的Ubuntu版本后,在ubuntu Branches下全选
拉至网页最下,点击生产,复制list下内容,添加到/etc/apt/sources.list中即可

修改镜像源之后需要重新更新:
sudo apt-get update
如果执行sudo apt-get update仍然报错,问题在于DNS没有配置好。
解决方法:
sudo vi /etc/resolv.conf
在其中添加:
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN nameserver 127.0.1.1 #这里用的是阿里云的DNS服务器 nameserver 223.5.5.5 nameserver 223.6.6.6
安装pip3:
sudo apt-get install python3-pip
