Run image based off Ubuntu 22.04 on R32.7.2 / Where is l4t:r32.7.2

(new users can only have one link per post, so I’ve hosted the question as a gist here with links: · GitHub)

On my Jetson Xavier NX board, I do

$ cat /etc/nv_tegra_release 
# R32 (release), REVISION: 7.2, GCID: 30192233, BOARD: t186ref, EABI: aarch64, DATE: Sun Apr 17 09:53:50 UTC 2022

If I’ve understood correctly, that means that I should build docker images off e.g.l4t-pytorch:r32.7.2, but I only see JetPack 4.6.1 (L4T R32.7.1) at

That’s probably stemming from the fact that there is no R32.7.2 at

I believe the Dockerfiles for those l4t-base images are at

Ultimately, I’d like to use an image like dustynv/ros:humble-pytorch-l4t-r35.1.0 (at, from

What goes wrong if I run an r35/r34 image on a Jetson with r32 installed?


Since some OS-related libraries will be mounted, please align the Linux version between Jetson native and the container.

For the r32.7.2 environment, please use the r32.7.1 container instead.
The container is the same if only the minor version updated.


Thanks for the information about the compatibility within minor versions.

What are our options for making a Dockerfile with more recent versions of Ubuntu as a base?

I have found these Dockerfiles: Files · master · nvidia / container-images / l4t-base · GitLab but it sounds like these Dockerfiles are not officially released, e.g. for R35, according to Dockerfile wanted - #7

Quick clarification, semver notation is major.minor.patch . The container images are the same if only the patch version is updated, to be sure.


You can find the l4t-base image for r35 below:
