Upgrading to JetPack 5.1 From Previous JetPack 5 Releases
If you are already running JetPack 5 on your Jetson Orin or Xavier, you can upgrade with having to use the SDK Manager. However, you may encounter an error. Here’s the directions from the forum post on how to install, and if you encounter an error, a workaround:
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.
If you run into trouble, ask questions on the Jetson forums!

Read the Release Notes!
Even though this is a point release, there are a lot of changes going on here. Some of these have to do with Over The Air (OTA) updates and security measures. Also, JetPack with all of the libraries and samples may not fit on a Jetson Xavier eMMC. There are methods to install only the libraries and get what you need.
You can save yourself a lot of time by reading the release notes. As usual, the release notes will help guide you through the new features, as well as point out some of the rough spots of known issues.
