Unable updatede?

Hello! I found that it is very difficult to access the official server in the China region where we are located. Now I can’t connect to the server even for update. Is there any better way? Can you suggest to establish a server in China for the convenience of Chinese developers?

We have build a mirror server at China, but seems still some room to improve.
I will highlight to our relevant team to improve it continuously.

Hello! How can I solve the situation shown in the picture? I can’t update on jetson xavier nx normally? According to the URL, I downloaded the release on the windows computer. How should I use it?

No route to host is an internet issue in most cases. It is true that the server could be down, but it is far more likely a route hop or firewall issue is actually the cause. However, consider that one of the addresses in the errors is this:
106.225.244.208

What do you see from “traceroute 106.225.244.208”? It is quite possible you’d need to get your ISP to help you. If NVIDIA can confirm that server is up, then you’ll know it is out of their hands for intermediate route hop failures/firewall issues.

Please help look at the following question

If this is one of the mirrors updating, then the error would clear up after a bit of wait time. If for some reason your apt cache is corrupt, then you could clean this (and it would then need to redownload software again in many cases):
sudo apt-get clean

You can see ahead of time what this would clean:
sudo apt-get clean --dry-run

If there is a network issue, then this won’t help. For network issues, if the issues are not from your own network, then your ISP would need to be consulted about fixes.

Thanks
