  E: Some index files failed to download. They have been ignored, or old ones used instead.

I executed ‘sudo apt install ntpdate’, and also downloaded and executed this shell script: jetcard/jetson_add_ntp_server.sh at master · NVIDIA-AI-IOT/jetcard · GitHub , but the error is still there, this has blocked me to install other software.

hello akachen,

we cannot reproduce the issue locally, this should related to the server issue,
i.e. https://repo.download.nvidia.cn/

could you please try revise the repo for verification.
thanks

How to revise the repo ?

[carolyuu]

Hi user30659,

Please open the apt source configuration file:
$ sudo vi /etc/apt/sources.list.d/nvidia-l4t-apt-source.list

And check the command would be:

deb https://repo.download.nvidia.com/jetson/common r32.6 main
deb https://repo.download.nvidia.com/jetson/t194 r32.6 main

Run ‘apt update’ again. Thanks!

[akachen]

Thanks, now ‘sudo apt update’ can run well, I did nothing since yesterday after I reported this case, as you said, it looks like your server has problem yesterday.
You can close this case now, thanks.
