Repository Release File Missing for Jetson Orin Nano

Issue Overview

Users are encountering an error when attempting to add a repository for the Jetson Orin Nano using the command suggested in the official NVIDIA documentation. Specifically, the command sudo add-apt-repository "deb https://repo.download.nvidia.com/jetson/common/orin-nano r35.3 main" is failing with a "404 Not Found" error, indicating that the release file for the repository is not available at the specified URL.

Possible Causes

1. Outdated documentation: The NVIDIA documentation may be referencing a repository structure that is no longer in use or has been changed.

2. Repository restructuring: NVIDIA may have reorganized their repository structure, making the specific Orin Nano repository obsolete.

3. Temporary server issue: There could be a temporary problem with NVIDIA’s repository servers, causing the release file to be inaccessible.

4. Incorrect repository URL: The URL provided in the documentation might contain a typo or be incorrect for the current repository structure.

Troubleshooting Steps, Solutions & Fixes

1. Use the common repository:
   According to an NVIDIA representative, the Orin Nano-specific repository has been deprecated, and all Jetson devices now use the same common repository. Update your repository configuration as follows:

   sudo add-apt-repository "deb https://repo.download.nvidia.com/jetson/common r35.3 main"
   

2. Remove the old repository entry:
   If you’ve already added the non-functioning repository, remove it using:

   sudo add-apt-repository --remove "deb https://repo.download.nvidia.com/jetson/common/orin-nano r35.3 main"
   

3. Update package lists:
   After making changes to your repository configuration, update your package lists:

   sudo apt update
   

4. Check for documentation updates:
   Visit the official NVIDIA Jetson documentation website to see if there are any updates or errata related to this issue. The documentation team has been notified and should be updating the instructions to remove the deprecated repository information.

5. Monitor NVIDIA Developer Forums:
   Keep an eye on the NVIDIA Developer Forums, particularly in the Jetson & Embedded Systems category, for any announcements or updates regarding repository changes or issues.

6. If issues persist:
   If you continue to experience problems after following these steps, consider reaching out to NVIDIA support or posting a new thread in the Jetson Orin Nano section of the NVIDIA Developer Forums with detailed information about your setup and the exact error messages you’re receiving.

By following these steps, you should be able to resolve the repository release file issue and proceed with your Jetson Orin Nano setup or development work.
