everything goes well but when i use docker run command it give this error 
Maybe docker it this KKE setup cannot run whalesay image.
And task don`t want from you to run containers.
Try something easier:
sudo docker run hello-world
If it runs well, so docker installation is ok.
i tried but same error
i think its not a problem with installation its due to the kernal version didn’t match so please check labs compatiblity.
sudo systemctl status docker result ok?
This lab don`t want to run containers at all.
Maybe authors setup task this way.
Completition task check got error as well?
