Original GitHub issue: https://github.com/RD17/ambar/issues/103
I followed the Ambar Installation: Step-by-step guide (https://blog.ambar.cloud/ambar-installation-step-by-step-guide-2/).
Download was successful.
If I start the ambar docker container with: sudo ./ambar.py start I get the following output and error:
`root@dc01:/opt/ambar# ./ambar.py start
