Cannot upgrade pip to the lastest version

General

Hi,
I’m using pip version 19.3.1; however, I want to upgrade pip to the lastest version 21.3.1 (which is available).
I type the code: “pip install --upgrade pip” in the doker. However, it does not work
I have a trouble with the following error:

Collecting pip

Consider using the --user option or check the permissions.

WARNING: You are using pip version 19.3.1; however, version 21.3.1 is available.
You should consider upgrading via the ‘pip install --upgrade pip’ command.
Note: you may need to restart the kernel to use updated packages.

I did restart the kernel and retry again but it still did not work

How can I do to solve this problem
could you help me please?
Best regards

This is unrelated to FEniCS.

You can either call
pip install --upgrade pip —user or
sudo pip install --upgrade pip
