FYI, that sounds like the separate driver for a desktop PC. Those don’t work on Jetsons. The GPU of a Jetson is integrated directly to the memory controller (an iGPU), whereas those other drivers expect a discrete GPU (dGPU) which is attached to the PCI bus. The two have a conflict.
When you flash a Jetson, or create that new SD card, it already has the correct driver. Beware that some applications may not detect this because they depend on the nvidia-smi
application, which in turn depends on the PCI bus.
L4T is what actually gets flashed (this is what they call it after adding NVIDIA drivers, including GPU, to Ubuntu). There is a JetPack flash tool that runs on a Linux PC with the correct Ubuntu release for flashing a Jetson. There is also sometimes a referral to software added to the Jetson via a package named after jetpack
, but this is different. JetPack/SDK Manager is often referred to, and this is what runs on another PC. The JetPack release is usually tied to the L4T release, so naming one release normally names the other’s release. You can find your L4T release with:
head -n 1 /etc/nv_tegra_release
Also, make sure you have the correct forum. This is the “Jetson Nano” forum. There is also a “Jetson Orin Nano”, which is very very different (and more expensive). Do you have an Orin Nano? If so, then JetPack 6 is good; if not, then you cannot use JetPack 6. You’d have to go back to JetPack 4. Here is the list of L4T releases (a table naming which product goes with the release):
https://developer.nvidia.com/linux-tegra
You can also look for JetPack releases (these are for host PC side, not direct install to Jetson):

However, you can sometimes (if versions are not too far off) start JetPack like this to see older L4T releases (you need R32.x for Nano, but R35.x or R36.x works for Orin Nano):
sdkmanager --archived-versions
(SDK manager is a smart network layer on top of JetPack and is how you start JetPack on the host PC on command line)
If you have just a Nano, then you are in the right forum. If this is an Orin Nano, go here:

(there are actually also in-between hardware, the TX2 and Xavier)
