`--allow-downgrades` in /opt/bin/setup

I had created custom AMI using AWS EC2 Image Builder which had docker and it's dependencies preinstalled. Now when I used this AMI in the machinedeployment, the /opt/bin/setup script was just giving this error.

supervise.sh[155349]: E: Packages were downgraded and -y was used without --allow-downgrades.

and due to /opt/bin/supervise.sh, the setup script just kept executing in an infinite loop and never completing the machine setup.
