@vishalkrtr I was wondering if you might be able to give more context around why or when this error occurred?

get-pip.py is a different GitHub project located here: https://github.com/pypa/get-pip. If your error is related to get-pip.py, as it appears to be, you will have more luck opening an issue with that project.

One thing you might want to try before opening a ticket with that project is running the command with elevated privileges. In Windows that would mean running in an Administrator command prompt. In Linux that would mean running sudo python get-pip.py.

A quick google search of your error message also shows that some Linux users have had success in fixing that issue by first installing the foreign function interface components before running get-pip.py. I would also try: sudo apt-get install python-cffi, then sudo python get-pip.py
