I've tried upgrading my kernel from 3.19.0-22 to any of the kernel 4.* releases in Ubuntu 15.04 but upon rebooting I've found that docker doesn't work anymore.

Sep 19 12:37:14 sniper docker[1098]:
time="2015-09-19T12:37:14.116981936+02:00" level=error
msg="[graphdriver] prior storage driver \"aufs\" failed: driver not supported"
Sep 19 12:37:14 sniper docker[1098]:
time="2015-09-19T12:37:14.117058280+02:00" level=fatal msg="Error
starting daemon: error initializing graphdriver: driver not supported"

My question is:

Am I missing something or am I supposed to do something for this to work?

Or is it something in docker that I can change so that it works again?

Thank you for your time and help.

  • @Pilot6 what do you mean that they are not supported in Ubuntu yet? They do appear in their mainline repository, kernel.ubuntu.com/~kernel-ppa/mainline and the system works otherwise without a problem. Thank you.

    I mean literally that these kernels are not supported. You can install them at your own risk. Some software may malfunction with these kernels, that is normal.

After installing linux kernel 4.2.1 for ubuntu (from ppa) docker stopped to function properly.

To get it back working I did:

After stopping docker service,

sudo apt-get remove --purge docker-engine

then I got rid of any former container and images that were still in aufs in /var/lib/docker

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

then I reinstalled docker from the script docker is hosting online:

wget -qO- https://get.docker.com/ | sh

docker instantly worked after reinstallation

I could probably copy and paste data from the /var/lib/docker.old so as to get containers and images, but that was not worth it in my case, so I didn't even try, but you migth consider to do this if you want to retrieve former images and containers.


I was have the same issue,and this solve the probelm
sudo rm -rf /var/lib/docker/aufs
and i suggest to use this command to install Docker
curl https://get.docker.com | bash
if this not solve the probelm there is many soultion in this :
