To upgrade from previous JetPack 5 Releases:

To upgrade from previous JetPack 5 releases, first edit /etc/apt/sources.list.d/nvidia-l4t-apt-source.list to point to the 35.2 repo (just change the version to r35.2 in both lines). Next, use the following commands, then physically reboot the system:

sudo apt update

sudo apt dist-upgrade

sudo apt install --fix-broken -o Dpkg::Options::="--force-overwrite"

If you encounter an error, please use the following 3 commands and re-attempt the upgrade (do not reboot the device after running below command and before re-attempting the upgrade)

sudo parted /dev/mmcblk0 -s rm 4

sudo parted /dev/mmcblk0 -s resizepart 3 67.9MB

sudo parted /dev/mmcblk0 mkpart -s A_reserved_on_user 67.9MB 101MB

Please select “Ignore” when prompted and “ext2” as the file system type.

Resources:

Note: Some of the links in Jetson Linux 35.2.1 page in Downloads section do not follow the normal convention. For example: https://developer.nvidia.com/downloads/r35releasev21-sources-ubuntufocal-l4taarch64srctbz2

Instead of

https://developer.nvidia.com/downloads/r35_release_v2.1/sources/ubuntu_focal-l4t_aarch64_src.tbz2

This is due to an issue in our posting tool and we plan to fix it within a week so that our links can follow the convention as before.

Update:

We found an issue when installing JetPack using SDK Manager where Jetson Multimedia installation was not succesfull. We have fixed the issue.
If you had already tried JetPack 5.1 installation using SDK Manager, please uninstall JetPack 5.1 using the SDK Manager menu in the left-bottom in the SDK Manager main GUI. Then close and re-open the SDK Manager, download and install JetPack 5.1 again.

Also note that the nvidia-jetpack metapackage is now avaialable in the APT repo. If you want to install JetPack after installing Jetson Linux 35.2.1 using APT, then just follow the familiar commands:

sudo apt update
sudo apt install nvidia-jetpack

Update:

Most of the containers for JetPack 5.1 are also up on NGC, except Tensorflow, Pytorch and ML container.

@suhash, Is the reference to Jetson Linux 32.5.1 intentional, or should it be 35.2.1?

Thank you.

@johnmansellis thanks for catching that. It is 35.2.1

The ML containers for JetPack 5.1 have been published on NGC here:

nvcr.io/nvidia/l4t-ml:r35.2.1-py3
nvcr.io/nvidia/l4t-pytorch:r35.2.1-pth2.0-py3
nvcr.io/nvidia/l4t-tensorflow:r35.2.1-tf2.11-py3

Absolutely new to Linux.
What does this mean?
"first edit /etc/apt/sources.list.d/nvidia-l4t-apt-source.list "
I know I need to be in the terminal
Just got my Orin and trying to update.

thx

Sorry for the late reply, this is telling you to edit a file in linux. The location of the file is at “/etc/apt/sources.list.d/nvidia-l4t-apt-source.list”. This would be the equivalent of saying on a windows machine, “first edit C:/Documents/User/some_document”

There are many ways to edit a file in linux. If you search for editing a text file in linux, you will find a number of resources and examples. Whichever one seems comfortable to you will be fine. Do take into account that if you are editing a file that your user doesn’t have permission to edit, you’ll want to open it with ‘sudo’ privileges. An example would be: sudo nano /etc/apt/sources.list.d/nvidia-l4t-apt-source.list which will open the file in the “nano” text editor with sudo access. (Super User Do). You can then edit the file and save it.
