pip install --upgrade pip breaks pip, still

Environment

• pip version: 10
• Python version: 2.7.12
• OS: Ubuntu 16.04

Description

I ran “pip install --upgrade pip”

now pip breaks, every time:

[J]~/bin >pip --version Traceback (most recent call last): File “/usr/bin/pip”, line 9, in <module> from pip import main ImportError: cannot import name main

I tried “sudo apt remove python-pip” and a full autoremove, and re-installed pip, and it’s still broken

Another ticket, from April 16 is now closed, relates to the same error message https://github.com/pypa/pip/issues/5240

How do we downgrade or fix this?

Expected behavior

How to Reproduce

1. Get package from ‘…’
2. Then run ‘…’
3. An error occurs.

Output

Paste the output of the steps above, including the commands themselves and
pip's output/traceback etc.

You probably don’t have the directory where the new pip is installed in your PATH. I think one of Ubuntu/Debian patches to pip is to install to /usr/local per default (when run as root, and without --user). Do you have a pip in /usr/local/bin?
