How to update Python version in root environment in cond

Question

A simple question: how to upgrade from Python 3.5 to 3.6 in my root environment in conda? That is, I do not want to create a new Python 3.6 environment; I want my root environment to change in Python 3.6

I tried

conda update --all python=3.6 

This is a package update, but not a version of Python.

I also tried

 conda install python=3.6 

I get UnsatisfiableError

Run this:

 conda install anaconda=4.3
