Das,
[following up from your direct message]
I can't tell what you did before the screenshot you shared but the errors you're seeing now are there because you have a partially set up environment which is now conflicting with the new attempt you are making. You need to clean up with:
./cleanup.shand then re-run:
./docker-setup.shIf you still get errors, please post these as a reply on this thread.
Jon.
