Your docker install is mixing two things up. You do not have the image with the id a1c22f3d250f used by the container with id 75ba5e06fcd2 (which used to be your old portainer).
I would recommend to delete the old container by docker container rm 75ba5e06fcd2 and try to get rid of this image
docker image rm a1c22f3d250f
If you are starting with docker-compsoe and bind a local directory, you can even try to remove the volume of the old container with docker volume rm portainer_data bt maybe before doing this, give me the output of docker volume ls and docker volume inspect portainer_data
