方法:Ubuntu配置网络源-apt源、pip源、conda源

apt源

方法1
编辑/etc/apt/sources.list:

sudo gedit /etc/apt/sources.list

写入，如阿里源

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse

方法2
搜索并打开应用"Software & Updates"，在"Download from:“中打开"other…”，选择国内的网络源，如下

pip源

编辑~/.pip/pip.conf，沒有則新建:

sudo gedit ~/.pip/pip.conf

写入，如阿里源

[global]
index-url = https://mirrors.aliyun.com/pypi/simple
trusted-host = mirrors.aliyun.com

conda源

编辑.condarc，沒有則新建:

sudo gedit ~/.condarc

写入，如阿里源
