Failure to load JetPack via SDK Manager

Hi, trying to reflash my Orin AGX 64Gb Dev Kit to R36 with JetPack dependencies. I can successfully reflash the board, but after when throwing the debian packages onto it I get this error log:

Internet connection.: Internet connection check failure.
command < ssh -F /dev/null -o PreferredAuthentications=password -o PubkeyAuthentication=no -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -o ConnectTimeout=5 kasti@192.168.55.1 ‘ping -c 3 nvidia.com || wget --spider -T 5 -t 1 www.nvidia.com’ > terminated with error, exitCode: 5.

Access to APT repository and ability to install Debian packages with it.: Apt repository check failure (1. sudo apt-get update && sudo apt-get check; 2. sudo dpkg --audit).

My Jetson is successfully connected to the internet, how could I fix this issue?

I don’t really know what the situation is as the log is not complete.
You can do

sudo apt update
sudo apt install nvidia-jetpack

directly on the device.
