When a try to run docker locally in ubuntu 14.04 when i run this line in the console:
sudo docker -d
The console show me this error:
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.
