Modify Ubuntu apt source

Open the / etc/apt/sources.list file, delete all the contents, add the following contents and save.

deb http://mirrors.zju.edu.cn/ubuntu xenial main universe restricted multiverse
deb http://mirrors.zju.edu.cn/ubuntu xenial-security main universe restricted multiverse
deb http://mirrors.zju.edu.cn/ubuntu xenial-updates main universe restricted multiverse
deb http://mirrors.zju.edu.cn/ubuntu xenial-backports main universe restricted multiverse
deb-src http://mirrors.zju.edu.cn/ubuntu xenial main universe restricted multiverse
deb-src http://mirrors.zju.edu.cn/ubuntu xenial-security main universe restricted multiverse
deb-src http://mirrors.zju.edu.cn/ubuntu xenial-updates main universe restricted multiverse
deb-src http://mirrors.zju.edu.cn/ubuntu xenial-backports main universe restricted multiverse

Be careful:
The apt source modified in this way is valid for all users of the same system

Modify Ubunt u's Python source

Under the user's own home directory, create a new folder named. Pip, and then create a file named pip.conf under the. PIP folder. The content of the file is as follows: save it finally.

[global]
index-url=http://mirrors.zju.edu.cn/pypi/web/simple
trusted-host=mirrors.zju.edu.cn
disable-pip-version-check =true

Be careful:
The pipy source modified in this form is only valid for the current user.
It is not recommended for users to install packages directly using pip install (it is easy to be unclear whether the packages installed are python3 or python2).
The following commands are recommended for installing python packages:

Note if you need to install the package for Python 3, use the following command: Python 3 - M PIP install numpy***
Note if you need to install the package for Python 2, use the following command: python2 -m pip install numpy***
