Docker container producing different results for same command

A colleague and I have a big Docker puzzle.

When we run the following commands we get different results.

docker run -it python:3.8.6 /bin/bash  pip install fbprophet  

For me, it installs perfectly, while for him it produces an error and fails to install. I thought the whole point of docker is to prevent this kind of issue, so I'm really puzzled.

I'm giving more details below, but my main question is:

• How is it possible that we get different results?

More details:

We both are running Docker in a new MacBook Pro with similar specs, on Catalina. His Docker engine version 20.x.x is slightly newer than mine 19.X.X. Also:

• He tried all the commands he could think of to clean up things in Docker.
• We verified that the hashes of the image IDs were the same.
• Our resource settings were also the same.
• He tried reinstalling Docker and changing to other versions of python (3.7).
• We tried simultaneously on multiple occasions during the last three days.

The result was always the same: He gets the error and I don't.

The error he gets is the following.

Optional additional questions:

• How do we fix it?
• How do we prevent non-reproducible results like this one?
• Can upgrading the docker engine version break a container?
