Description:

This is my first time to install pip in my Ubuntu 18.04 LTS that I have just installed for serveral days. After using “curl” command to download the “get-pip.py” file and running the command “python3 get-pip.py”, I got the error message. The error message is following.

What I’ve run:

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

python3 get-pip.py

The error message:
