How to upgrade AWS CLI to the latest version?

Question

I recently noticed that I am running an old version of AWS CLI that is lacking some functionality I need:

$aws --version
aws-cli/1.2.9 Python/3.4.3 Linux/3.1         


        

Answer 1

This does not work:

pip install --upgrade awscli

This worked fine on Ubuntu 14.04( no need to reboot also .. You would have to first install pip3 ):

pip3 install --upgrade awscli
