Proper way to install pip on Ubuntu

Question

I\'m trying to install the latest version of pip (currently 8.1.2) on the official ubuntu/trusty64 Vagrant box. The box comes with Python 2.7.6 and 3.4.3 pre-installed with apt-

Answer 1

This worked for me on ubuntu 18.0.4:

1- sudo apt-get update
2- sudo apt-get upgrade
3- sudo apt-get install python-pip
4- pip -V

Answer 2

The proper commands to install pip and pip3 should be the following:

sudo apt-get install python-pip python3-pip --yes
sudo python3 -m pip install pip --upgrade --force-reinstall
sudo python -m pip install pip --upgrade --force-reinstall # this must come after upgrading pip3

The last two lines get pip3 and pip up-to-date. The last line is critical because it re-associates pip with python 2.
