I have this error since two weeks, and I don’t understand how can I resolve it. I’m trying to create very slim image without lucky

>Solution :

A good practice when creating docker images is to set a tag to the image you are using to avoid breaking changes from version to version like so: FROM debian:12-slim. Otherwise its going to use the latest tag and download whatever is latest.

The message is very clear.
