pip upgrade failure. - Githubissues

I've found this bug when trying to upgrade pip to 10. Without it I am unable to install Django 2.x.x with python 3.x.x.

I couldnt find a fix for it so I'll copy this over here and see if you guys have any solutions.

Pip version: 10.0.0
Python version: 3.5.2
Operating system: POP_OS 18.04

Description:

When upgrading pip (to v10) on at least Ubuntu 16.04, the pip3 command stops working ("cannot import main", see below). This is on a fresh install. What I've run:

(Note that I've stripped out all the apt output etc., since I think it's not needed here. Let me know if you still want it!)
