When i want to remove some unused image with name "" in docker i face with the problem unable to delete a354bbc7c9b7 (cannot be forced) - image has dependent child images.So for solving this problem:

sudo docker ps -a

you can see that i have several Images with name javaapp:latest and different container name. So, i killed and remove all container of "javaapp:latest" container with:

sudo docker stop "containerName"

sudo docker rm "containrName"

Then

sudo docker rmi -f "imageId"

So i can remove all the images with name ""

goodluck
