Answer 1

In ubuntu 18.04.1 Bionic Beaver, you need to log out and log back in (restart not necessary) to get the proper environment.

$ sudo apt install python-pip

$ pip --version
pip 9.0.1 from /usr/lib/python2.7/dist-packages (python 2.7)

$ pip install --upgrade pip

$ pip --version
Traceback (most recent call last):
  File "/usr/bin/pip", line 9, in 
    from pip import main
ImportError: cannot import name main

$ exit


$ pip --version
pip 18.1 from /home/test/.local/lib/python2.7/site-packages/pip (python 2.7)
