you can follow these steps and this will work for you:

1. create a docker group sudo groupadd docker
2. add your user to this group sudo usermod -aG docker $USER
3. list the groups to make sure that docker group created successfully by running this command groups
4. run the following command also to change the session for docker group newgrp docker
5. change the group ownership for file docker.socksudo chown root:docker /var/run/docker.sock
6. change the ownership for .docker directory sudo chown "$USER":"$USER" /home/"$USER"/.docker -R
7. finally sudo chmod g+rwx "$HOME/.docker" -R

After that test you can run docker ps -a
