Unable to find file /etc/nv_tegra_release running jetsonUtilities tool

Autonomous Machines Jetson & Embedded Systems Jetson TX2

When I try to run jetsonUtilities on XT2 to check the current L4T version, I’m getting
Reason: Unable to find file /etc/nv_tegra_release

I went to /etc/ and indeed the file is not there, what I’m doing wrong.
I’d like to upgrade the current JetPack version but first I need to determine which one the XT2 from stock is coming with.

Thanks

This means that the “apply_binaries.sh” step was not done. Basically the sample rootfs is pure Ubuntu, but drivers and other software providing direct hardware access support gets added on top of this…it is this latter step which is missing. Did you flash on command line? If so, did you skip the “sudo ./apply_binaries.sh” step? If you used JetPack I’d be surprised this is missing, but JetPack just does this step as well.

FYI, if you have a module which was not part of a dev kit, then no o/s comes installed.

Thank you for such a detailed answer.
As you pointed out, the missing step was to flash the latest Jetpack, once I did it, all I needed started working like a charm.
including Docker Engine, what actually I needed the toy for

Thanks
