Docker build command fails with manifest not found error

I received the attached error and I run the docker build -t webapp-color:lite . for question 14 for the docker images section of the Docker Training Course for the Absolute Beginner

manifest for python:3.6-alphine not found: manifest unknown: manifest unknown

Does anyone have an idea of what could be the issue with the lab?

Spell alpine correctly and it will work :slight_smile:

Thank you and I will try again
