一，更换系统源：
首先备份系统源
sudo cp /etc/apt/sources.list  /etc/apt/sources.list.bak
将sources.list更换成下面的源
清华大学源：

deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricted
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates main restricted
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial universe
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates universe
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security main restricted
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security universe
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security multiverse

更新下源
sudo apt-get update

二，更换pip源
在用户(/home/name/)目录下创建.pip文件夹，并创建pip.conf文件
Linux下，修改 ~/.pip/pip.conf (没有就创建一个文件夹及文件。文件夹要加“.”，表示是隐藏文件夹)

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

windows下，直接在user目录中创建一个pip目录，如：C:\Users\xx\pip，新建文件pip.ini。内容同上。

I think,
more intelligent choice is required
to, at first, determine the address, e.g., domestic or international,
and then,
to, choose the proper pip/apt source

anyway,

this is very useful and solves my big problem
