Respected Sir/Madam,

I was trying to install CUDA for Jetson AGX orin 32GB

But it came error in the step ```
sudo dpkg -i cuda-repo-ubuntu2004-11-7-local_11.7.0-515.43.04-1_arm64.deb

ERROR: The public CUDA GPG key does not appear to be installed. To install the key, run this command:
sudo cp /var/cuda-repo-ubuntu2004-11-7-local/cuda-77E18803-keyring.gpg /usr/share/keyrings/

After this error, I just shut it down and turned it on after 15mins. But now the orin does not show any display output it appears as a blank screen. (the display monitor light blinks)
