Good Day TLK Team,

This is the error message I am getting when I get to the Pulling phase.

alchemistclubstudios@alchemistclubstudios:~$ docker login nvcr.io

Hi johnnymystic19,
I think you may get the same error when you run below command
$ docker run helloworld

Please run below to fix your issue.

  1. Firstly, check whether there is a user group for docker.
    $ sudo cat /etc/group | grep docker
  2. If not, then create the docker group.
    $ sudo groupadd docker
  3. Add your user to the docker group.
    $ sudo usermod -aG docker $USER
  4. double check
    $ sudo cat /etc/group |grep docker
  5. Restart docker
    $ sudo systemctl restart docker
  6. check below commands again.
    docker run helloworld docker login nvcr.io
