Linux 系统配置网络问题

1. 设置sources.list源

参考： https://blog.youkuaiyun.com/u010368556/article/details/104965055

备份源列表

首先备份源列表
sudo cp /etc/apt/sources.list /etc/apt/sources.list_backup

编辑sources.list

sudo vim /etc/apt/sources.list

Ubuntu 18.04 TLS版本清华镜像源：

# https://mirrors.tuna.tsinghua.edu.cn/help/ubuntu/
# 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/ bionic main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse
 
# 预发布软件源，不建议启用
# deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse

刷新列表，一定要执行刷新

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install build-essential

2. 配置pip 国内源

永久配置清华源

mkdir ~/.pip
vi ~/.pip/pip.conf

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

3. 配置conda 国内源

编辑 ~/.condarc

gedit ~/.condarc

添加以下内容

auto_activate_base: false
channel_priority: flexible
channels:
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
  - https://mirrors.ustc.edu.cn/anaconda/cloud/conda-forge/
  - https://mirrors.ustc.edu.cn/anaconda/pkgs/free/
  - https://mirrors.ustc.edu.cn/anaconda/pkgs/main/
  - defaults
