Apt upgrade fails on fresh zed box flash

It appears that Nvidia’s repos have changed such that the apt update fails after a fresh flash of a zed box orin nx 16gb using stereolab’s flashing script with this error

Context:
I flashed one zed box orin nx 16gb board last week successfully. After performing an apt upgrade, the output of dpkg -l | grep nvidia-l4t-core is 36.4.320250107174145. This aligns with the version downloaded in the flashing script. This apt update succeeded.
After flashing another identical zed box this week, apt update fails and the output of the above version is 36.4.4-20250616085344.

Is there an updated flashing process available?

Hi @jdcast
what’s the output of the command cat /etc/nv_tegra_release?

This is before the apt upgrade:

R36 (release), REVISION: 4.3, GCID: 38968081, BOARD: generic, EABI: aarch64, DATE: Wed Jan 8 01:49:37 UTC 2025

KERNEL_VARIANT: oot

TARGET_USERSPACE_LIB_DIR=nvidia
TARGET_USERSPACE_LIB_DIR_PATH=usr/lib/aarch64-linux-gnu/nvidia

We are working on a new ZED X Driver v1.3.1 that will fix this problem introduced with the latest NVVIDIA upgrade.

Do you have a release date in mind for this?

I’m not sure how to proceed with reflashing in the meantime.

We are performing the latest QA tests. If everything is good, we can release the upgrade in a few days.
If we need to fix some modules, the release can happen in a few weeks.

In the meantime, what is the recommended approach to reflashing in a non broken state?

Is it possible to pin apt repository versions?

@jdcast Just ran into this myself, I had to reflash (there may have been a way to fix it without that but for me reflashing was easier). Once your system is in a working state, make this file to pin the packages until the driver is fixed. Once it’s fixed you should just be able to delete this file:

sudo vim /etc/apt/preferences.d/jetson-l4t-pinning

Contents:

Package: nvidia-l4t-*
Pin: version 36.4.3*
Pin-Priority: 1001

Package: nvidia-jetpack*
Pin: version 6.2+b77
Pin-Priority: 1001

You should be free to run update/upgrade without issues with this file in place. Note I was flashing jetpack 6.2, the nvidia-jetpack version might be different if you are installing 6.1, etc. But you can check it with apt search nvidia-jetson and just pin it to whatever it currently is

@Waelyn thank you for this temporarily fix.
The ZED X Driver v1.3.1 will be ready soon.
