I am trying to follow the instructions on installing the pre-empt RT kernel through apt found here:
Installing the jetson linux real-time kernel package
However the package seems to not be available as I get the following error:

Checking back it seems that R32.6 has the package but it’s not available in newer releases. Can you please advise if this is intended or its missing? Thank you.
