The rebuild won’t work. any help?

@Falco

Another work-around is adding a base_image key to the top level of the app.yml with the value of an older base image. Since we don’t even try to keep compatibility of the new images being able to run older Discourse versions this may be necessary if you are going back long enough.

Yeah doing historic installs is not going to be easy, recommend you choose an earlier base image. You can control that with the base_image: .... element.

Try adding the mentioned key and using an older image from https://hub.docker.com/r/discourse/base/tags
