prior storage driver "aufs" failed: driver not supported Error starting daemon: error initializing graphdriver: driver not supported

Try removing all downloaded images:

sudo rm /var/lib/docker/aufs -rf

That helped me to recover docker after a kernel update.

I had the same problem after a kernel update that removed the AUFS driver. What fixed it was:

sudo apt-get install linux-image-extra-`uname -r` && sudo modprobe aufs

If future updates break the driver again, bundle the command with your update:

sudo apt-get update && sudo apt-get upgrade && apt-get -y install linux-image-extra-$(uname -r) aufs-tools

For differences between apt-get upgrade and dist-upgrade, see Why use apt-get upgrade instead of apt-get dist-upgrade?.

As mentioned in ask Ubuntu, unfortunately you have to completely purge your previous docker installation by running:

sudo apt-get purge docker-engine

resp.

sudo apt-get purge docker.io

then you have to remove /var/lib/docker (Or move it to a different name, if you first want to try if everything works.)

sudo rm /var/lib/docker

resp.

sudo mv /var/lib/docker /var/lib/docker.old

Afterwards you can install the docker-engine package again.

The same procedure applies for debian.
