Error when creating a docker image using the default Dockerfile used in streamlit-demo for example

[masalinas]

Description of your problem

I used pyscaffold to generate a basic scaffolding project and add a simple flask module inside, everything is configured and works ok from my shell, starting my flask server correctly. I used the repo streamlit-demo from pyscaffold organization, because the scaffolfing tool not generate any Dockerfile inside the project so I followed the same Dockerfile template from this repo.

But when execute this Dockefile the step: Step 20/26 : RUN mamba env create -f environment.yml rsponse always with errors.
