Unable to Pull NVIDIA Aerial Container on DGX Spark – Authentication / Access Denied Issue

Hi Team,

I am setting up a new DGX Spark system to run NVIDIA Aerial (AI‑RAN) simulations for a proof‑of‑concept project. This is my first time configuring DGX Spark and NGC access, so I am following the official documentation.

Steps I have completed so far

  1. Logged into the DGX Spark machine (Ubuntu-based system).

  2. Tried verifying GPU access with:

    docker run --rm --gpus all nvidia/cuda:12.2.0-base nvidia-smi

    → The image was not found locally, so it failed.

  3. Created an NGC account and generated an API key/token.

  4. Logged into NGC using:

    docker login nvcr.io
Username: $oauthtoken
Password: <my NGC API key>

    → Docker reported “Login Succeeded”.

  5. But ~/.docker/config.json remains empty (no auth token stored).

  6. When attempting to pull Aerial:

    docker pull nvcr.io/nvidia/aerial/aerial:latest

    I get this error: denied: you are not authorized to access this resource

Current Issue

  • I created the NGC account myself, and I have not been added to any specific NVIDIA enterprise organisation or Aerial entitlement group.

  • This DGX Spark is new, and I want to run Aerial simulations for demonstration and testing.

  • It is unclear whether DGX Spark automatically includes Aerial access or if additional entitlement is required.

Request for NVIDIA Support

Could you please clarify:

  1. Do I need to be added to any special NVIDIA Aerial entitlement group to access:
    nvcr.io/nvidia/aerial/aerial ?

  2. Is Aerial available for DGX Spark users by default, or does an admin need to provide enterprise access?

  3. Why does docker login nvcr.io not write credentials into config.json?

  4. What are the correct steps to authenticate and pull Aerial containers on DGX Spark?

Any guidance or documentation links would be greatly appreciated.
Thank you!

Hi, please log into NGC then review all available CUDA images here cuda | NVIDIA NGC

I don’t believe aerial:latest image exists as spelled. To find Aerial related NGC images, please review the following query GPU-optimized AI, Machine Learning, & HPC Software | NVIDIA NGC. (will need to login first)

Logged in to NGC using- docker login nvcr.io

Tried pulling the Aerial 25.1 containers: docker pull nvcr.io/nvidia/aerial/aerial-sdk:25.1

docker pull nvcr.io/nvidia/aerial/aerial-sim:25.1

docker pull nvcr.io/nvidia/aerial/aerial-gnb:25.1

GPU, Docker, CUDA container, and NGC login all work successfully—

only Aerial repository access is denied.
