9. Unresolved Aspects:

   • Users may still need assistance with specific errors encountered during installation or configuration.
   • Further investigation into dependency issues or repository configurations may be necessary if standard troubleshooting does not resolve the problem.

By following these steps, users should be able to troubleshoot and successfully install Qt 5.15 on their Nvidia Jetson Orin Nano devices for their development needs.
