Cannot connect to the Docker daemon at unix:/var/run/docker.sock. Is the docker daemon running?
You can try out this:
systemctl start dockerIt worked fine for me.
P.S.: after if there is commands that you can't do without sudo, try this:
gpasswd -a $USER docker
Just Run
sudo dockerddockerd is the daemon service for docker containers, because it is not running in background we're not able to take any actions related to the service, which needs be restarted.
You can get this error if docker doesn't shut down cleanly. The following answer is for the docker snap package.
Run snap logs docker and look for the following:
Error starting daemon: pid file found, ensure docker is not running or delete /var/snap/docker/179/run/docker.pidDeleting that file and restarting docker worked for me.
rm /var/snap/docker/<your-version-number>/run/docker.pidsnap stop dockersnap start dockerMake sure to replace <your-version-number> with the appropriate version number.
