ImportError: cannot import name 'Literal'

Receiving the below outputs after (seemingly) successfully installing on a Lockheed Martin firewalled linux machine and attempting to run scenarioBasicOrbit.py :

Has anyone ever seen this? I am unsure what's going on. I should be passed all of the fire wall stuff at this point and this seems unrelated.

Thank you
Kenny

What version of Python are you using? python --version

[ObiWanKenoble]

I am using Python 3.6.8

[patkenneally]

That's the issue. Basilisk requires Python 3.7 and above. I would recommend you use 3.9 and up generally.

Yep, that was it. Thanks!
