Can't install realtime kernel on jetpack 4.6.1

[emessulam]

Can’t install realtime kernel on jetpack 4.6.1 on my Xavier AGX.
I’ve tried:

echo "deb https://repo.download.nvidia.com/jetson/rt-kernel r32.7 main" | sudo tee -a /etc/apt/sources.list.d/nvidia-l4t-apt-source.list

sudo apt update

sudo apt install nvidia-l4t-rt-kernel nvidia-l4t-rt-kernel-headers

But:

We’re checking with internal team, will do the update once clarified. Thanks

Any news?

Seems https://repo.download.nvidia.com/jetson/rt-kernel no longer available. Is it preferred to compile with PREMPT_RT patch ourselves again?

The rt-kernel was posted on the public APT server, issue should be fixed.
