Tried several networks, the problem still the same.

What should I do to make update working?

Hello,

Thanks for visiting the NVIDIA Developer Forums.
To ensure better visibility and support, I’ve moved your post to the Jetson category where it’s more appropriate

Cheers,

Hi,
It may be temporary server down. Could you please try again?

Hi, it seems it is an issue with the server but if the issue persist, could you try and run both of these commands to diagnose the issue:
getent ahosts ``repo.download.nvidia.com

curl -Iv --connect-timeout 10 ``https://repo.download.nvidia.com/jetson/common/dists/r36.5/InRelease

I hope this is useful.
