NO_PUBKEY Error During apt-get update on Jetson Orin Nano with JetPack 6.1

Hello Support Team,

I encountered the following error while attempting to update my package sources (apt-get update) on my Jetson Orin Nano Developer Kit running a clean installation of JetPack 6.1 with SDK Manager:

W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://isaac.download.nvidia.com/isaac-ros/release-3 jammy InRelease: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY BBE5EA6DE681BCAB

It seems that the corresponding GPG key is missing to validate the sources. Could you please provide guidance on how to correctly add the missing key, or let me know if there is an update to the package sources that resolves this issue?

Thank you in advance for your assistance!

Best regards,
Jürgen

And check if the network access works as expected on your board.
