@suhash I saw JP 4.6.2 has been released on the SDK manager; however, I noticed that the update notes are not posted on Archived Documentation For Jetson Software where they usually are. Is there any place where I can find the changes/fixes for this version?

@d57montes JP 4.6.2 (L4T 32.7.2) is a minor update on top of JP 4.6.1 (L4T 32.7.1) which bring only security fixes. All other things remain the same. We are updating our pages as we speak for 4.6.2.


I’m trying to flash the Jetson TX2 with the Jetpack 4.6.2 but I’m getting the following from the SDK Manager’s Terminal:

17:52:47 ERROR: File System and OS - target_image: E: The repository ‘ stable InRelease’ is not signed.

17:52:47 ERROR: File System and OS - target_image: command terminated with error

17:52:47 SUMMARY: Flash Jetson TX2 - flash: Depends on failed component

Is there anything that I’m doing wrong?
