Can't do apt update: public key is not available: NO_PUBKEY 1A2E4274AC7A8482

Doing a simple

apt update

I get:

W: GPG error: file:/var/libopencv4tegra-repo  Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 1A2E4274AC7A8482
E: The repository 'file:/var/libopencv4tegra-repo  Release' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.

Any ideas on this? I searched but I didn’t see anyone else havnig that problem. It looks like if I could find the key server for that I could import the key but I can’t.

Any suggestions welcome…

Hi MLLearner,

How do you hit this error? Does it happen when using Jetpack??

Just checked, this should be a warning message and not cause further error.

This is mentioned in release note.
