Description

Hi

After the issue with kernel version was fixed, i can now check my array kit. However, when i try to load AVS, i get the following issue:
env) pi@raspberrypi:~ $ alexa-auth
Traceback (most recent call last):

What I Did

i saw a previous posting and the recommendation of uninstalling tornado and reinstalling, however the same issue persists
