Hi, Tauqeer.

How did you install Python 3.6?

This is what you should see in Bio-linux 8 (Ubuntu 14.04.5 LTS):

> apt list 'python[0-9].[0-9]'

Please post the output from:

> sudo apt-cache policy 'python3'
> sudo apt -f install

I suspect that you have packages with dependencies that can't be
installed, which gives you the red warning that mean "fix it manually".

HTH,
