I'm taking a docker image, ubuntu/python:3.12-24.04_stable.
Dockerfile
FROM ubuntu/python:3.12-24.04_stable
RUN apk update
When I build this simple Dockerfile, I get exit code: 1. Is this docker image not available /bin/sh?
docker build -t test -f Dockerfile .

I've tried using python:3.12 and ubuntu:24.04 and all of them are working fine but the image only ubuntu/python:3.12-24.04_stable is returning the error to have RUN or so.
This is equivalent to a distroless image:
This image is a chiselled Ubuntu rock that contains only the Python runtime and its standard libraries. It is production-ready and can also be used as a base if additional application dependencies are needed.
(Source: the Hub overview)
The image contains no shell, no apt package manager, or anything other than the python binary and its dependencies:
