Docker broken after upgrade

sudo systemctl start docker
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

sudo journalctl -xe

Error starting daemon: error initializing graphdriver: /var/lib/docker contains several valid graphdrivers: devicemapper, overlay2; Please cleanup or explicit

sudo vi /etc/docker/daemon.json

append this at the end and before the closed curly brace:

,"storage-driver": "devicemapper"

sudo systemctl reset-failed docker.service
sudo systemctl start docker.service
