Jetpack 4.6.2 or 4.6.1 signature issues?

Hi I’m trying to flash a Jetson TX2 with Jetpack 4.6.1 or 4.6.2 with both cases I experience the following failures depicted in SDK Manager’s terminal (this terminal sample is with Jetpack 4.6.1):

What am I doing wrong?

Hi igal,

The above two errors indicate your host environment issue. Some deb on your machine added http://dl.google.com/linux/chrome/deb to the apt repository on your host machine, however, it is causing error of “sudo apt update” command.
Please fix the environment issue first, make sure “sudo apt update” command runs successfully on your host, then retry installation with SDK Manager.
