I’m trying to install nvblox on ubuntu22.04 on my Jetson agx orin. I successfully downloaded and launched the isaac_ros_nvblox package last week without updating the docker environment, so I have to rebuild the whole package again when I get into the docker environment. But when I tried to reinstall the nvblox following the steps in quick start, I got an error in sudo apt update, the following are the detailed error.

Same here, although in my case, for what it is worth, I was trying to rebuild the reference flow for rtdetr. Same issue though.

I also have this problem when trying to access any deb packages from https://isaac.download.nvidia.cn/isaac-ros/release-3/dists/jammy/release-3.0

Best,

I tried it 5 minutes ago, and it seems that the error occurs again.

After reflash my Jetson, the problem didn’t occur again.
