volttron installation certificate error

Question

I just downloaded the volltron files today from github. When I got to the step to execute:

python bootstrap.py

I got certificate verification errors. Below is the terminal snippet. Has anyone else encountered this?

Are you connected to the internet when you run bootstrap.py? — Kyle Monson, Nov 16 '17 at 22:29
Yes. I am posting to this website from the same computer. From a firewall perspective, SSL is allowed outbound on my computer and the network. — I. Aguilar, Nov 17 '17 at 14:23

It seems that the error in the development of Virtual Environment for Volttron. I got the same issue. I am using Ubuntu 16.04.

To solve the problem, I followed the steps below to create Virtual Environment http://www.pythonforbeginners.com/basics/how-to-use-python-virtualenv

These are the steps followed using the above link:

Install Virtualenv

$ sudo apt-get install python-virtualenv

after that:

mkdir ~/virtualenvironment

and

virtualenv ~/virtualenvironment/my_new_app

Lastly, activate your environment:

source activate

and to exit the virtualenv just type “deactivate”.

another easer way at: https://stackoverflow.com/a/3844055

in the first step I named the "virtualenv" volttron,

so it will be written as

$ virtualenv volttron

once I typed the above script in Volttron root, the python virtualenv created under, volttron/bin/python

New python executable in volttron/bin/python

Installing setuptools............done.

So, to activate in this case: we need to type: source volttron/bin/activate

I was able to create agents after doing these steps.

Please let me know if there is any easier way than this.

Thanks,

NOTE: if you do not have the "virtualenv" package, you can install it using : sudo apt install virtualenv
