I am trying to start docker service, but it shows me the below error.

Hi@akhtar,

It means the previous PID file of docker service is still available. So when you try to start your docker service, it can't start the service because one process id is already present. To avoid this error, you have to remove the previous PID file and then try to start your service.

$  rm -rf /var/snap/docker/179/run/docker.pid
$ systemctl start docker

Did you get any error? If yes then share your error.

$ rm -rf /var/run/docker.pid
rm: cannot remove '/var/run/docker.pid': Permission denied

Hi,

You need to run the command with Sudo power or from the root user. Otherwise, it will give you the above error.
