Unable to Access APT Repository and Install Debian Packages on Nvidia Jetson Orin Nano

Issue Overview

Users are experiencing difficulties accessing the APT repository and installing Debian packages on the Nvidia Jetson Orin Nano developer board. This issue is occurring during the installation of Jetpack 5.1.3 using the SDK Manager. The system is running Ubuntu 20.04.6 LTS. The SDK Manager detects that the system is not ready for installation and reports specific errors related to APT repository access and Debian package installation.

The error message indicates a failure in the APT repository check, specifically mentioning issues with updating the package list and performing a package integrity check. The command executed by the SDK Manager to verify system readiness times out after 200 seconds, resulting in an exit code of 124.

Possible Causes

1. Network Connectivity Issues: The developer board may not have a stable internet connection, preventing it from reaching the APT repositories.

2. Firewall or Proxy Settings: Incorrect firewall configurations or proxy settings could be blocking the connection to the APT repositories.

3. Corrupted Package Manager: The APT package manager on the system might be corrupted or misconfigured.

4. Insufficient Permissions: The user account may not have the necessary permissions to perform system updates and package installations.

5. Outdated System: An outdated system or incompatible software versions could lead to conflicts with the APT repository access.

6. Hardware Issues: There might be hardware-related problems affecting the network interface or system stability.

Troubleshooting Steps, Solutions & Fixes

1. Verify Network Connection:

   • Ensure the Jetson Orin Nano is connected to the internet.
   • Test the connection by pinging a known website:

     ping google.com
     

2. Update APT Package List:

   • Run the following command to update the package list:

     sudo apt update
     

   • If successful, proceed to install the Nvidia Jetpack:

     sudo apt install nvidia-jetpack
     

3. Check APT Configuration:

   • Verify the APT sources list:

     cat /etc/apt/sources.list
     

   • Ensure that the appropriate repositories are listed and not commented out.

4. Verify System Time:

   • Incorrect system time can cause SSL/TLS issues. Check and update if necessary:

     date
     sudo timedatectl set-ntp true
     

5. Clear APT Cache:

   • Remove the existing package cache and recreate it:

     sudo rm -rf /var/lib/apt/lists/*
     sudo apt clean
     sudo apt update
     

6. Check for Disk Space:

   • Ensure there’s enough free disk space:

     df -h
     

   • If the disk is full, remove unnecessary files or expand the storage.

7. Verify Package Manager Integrity:

   • Run a package manager consistency check:

     sudo dpkg --audit
     sudo apt-get check
     

8. Disable IPv6 (if necessary):

   • Some networks may have issues with IPv6. Temporarily disable it:

     sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
     sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1
     

9. Check for Conflicting Processes:

   • Ensure no other package management processes are running:

     ps aux | grep -i apt
     

   • If found, wait for them to finish or carefully terminate them.

10. Manually Install Jetpack:

    • If the SDK Manager continues to fail, try manually installing Jetpack components:

      sudo apt install nvidia-jetpack
      

11. Review System Logs:

    • Check for any relevant error messages in the system logs:

      sudo journalctl -xe
      

12. Contact Nvidia Support:

    • If all else fails, reach out to Nvidia support with detailed information about your system configuration and the steps you’ve tried.

Remember to reboot the system after making significant changes. If the issue persists after trying these solutions, consider performing a fresh installation of the operating system, ensuring you have the latest compatible version for your Jetson Orin Nano developer board.
