My device is unable to connent to the Internet so I could not use apt commands, when I run dpkg -i nvidia-l4t-kernel_5.10.120-tegra-35.4.1-20230801124926_arm64.deb I got the following message:

Hi,

I don’t feel like you can do it this way.
How did you get the deb package for 5.10.120 kernel?
There’s a lot of dependencies between stuff in the BSP, so you have to update the BSP as a whole, but something like just updating the kernel.

HI,
Thank you for your reply. I downloaded the package from Index.
I have just started to learn about these things, I’m still quite confused about all these stuff. What should I do to update the BSP as a whole?
I did read this page Software Packages and the Update Mechanism — Jetson Linux Developer Guide documentation and I thought that manually downloading and installing these packages listed in the table under Update Packages for Jetson Devices would be equivalent to using apt update. Is this the right thing to do?

Apparently is’t not.
If your device does not have access to the Internet, then I’d suggest considering imaged-based OTA:

I’ll give it a try. Thanks again.
