I'm setting up Docker for some machine learning tests, following the guide from the official Docker website. I can run the hello-world container and check the Docker version, but I'm hitting a roadblock. When I try to enable the Docker service with the command `sudo systemctl enable docker.service`, I get an error saying that the docker.service doesn't exist. This is confusing since Docker seems to be running fine. When I try to run the command `sudo docker run --rm --runtime=nvidia --gpus all ubuntu nvidia-smi`, it doesn't work either. I don't know why I can run Docker commands but still face this issue. I'm looking for some clarity on how to fix this problem so I can proceed with my project.

It sounds like there might be an issue with the Docker daemon not running properly. First, check if the Docker service is active by running `sudo systemctl status docker`. If it shows that it's inactive or not found, you might need to start it with `sudo systemctl start docker`. Also, make sure you've installed the nvidia-container-toolkit, as that's crucial for running GPU containers. Check your OS version too—some commands might differ slightly based on your Linux distro.
You might not have the Docker service installed correctly. Try reinstalling Docker using the official guide, and double-check that you're using the correct version for your OS. Make sure to follow the installation steps for the nVidia toolkit, too; it can be a bit tricky! Sometimes the service name can vary, so it’s worth checking. If everything else fails, check the Docker logs for more clues about what's going wrong.
Thanks for the tips! I checked the status, and it says inactive. I'll try starting it and see if that helps.
