Not being able to remove docker images with "docker image prune -a"

I have two docker images that I would like to remove, but it seems that they cannot be removed with docker image prune -a. Why? The two images are not used in the terminal, since I just restarted the terminal.

(base) ~ % docker image ls
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

(base) ~ % docker image prune -a

How can I remove the images?

You'll need to make sure all Docker containers are stopped and removed, after that you can remove the Docker images.

Stop and remove all docker containers and images:

  1. List all containers (only IDs) docker ps -aq.
  2. Stop all running containers. docker stop $(docker ps -aq)
  3. Remove all containers. docker rm $(docker ps -aq)
  4. Remove all images. docker rmi $(docker images -q) or docker image prune -a

docker image prune only remove images not currently associated with a container.

You may want to use docker rmi [image id] (example docker rmi 245e34778213) instead.
