Troubleshoot

Sometimes you may find it difficult to remove a container. Then manually remove the container would help

# stop docker
sudo /etc/init.d/docker stop
# list containers in your machine
sudo ls /var/lib/docker/containers
# Identify the container you want to remove
sudo rm -r /var/lib/docker/containers/<contaner-id>
# start docker
sudo /etc/init.d/docker start
