Docker Image copying image in the datastore

Hello everyone i resolved this issue .

the problem is in the installation of docker in your machine .
first you should run :

apt-cache policy docker*

**
after that you will see : docker and docker.io not installed
for example :
image

after that run :

apt install docker

and

apt install docker.io

docker.io will remove automatically docker-ce
finally you should see :



image
