why opkg update failed?

I tried many many times.

Hey. Assuming you're using the normal build workflow, your bitbake actions are run within the pyrex docker container. It's possible that DNS resolution within the container environment is messed up.

After sourcing the ni-oe-init-build-env script, try running

pyrex-run wget 'http://download.ni.com/ni-linux-rt/feeds/2022Q3/ni-main/Packages.gz'

or your ping command again.

The pyrex-run wrapper script will pass your command into the docker execution environment. If it fails in that context, then there is something off with your docker configuration. I can't help too much with that, since it is specific to your build machine.

But you might have to add this to your host machine's /etc/docker/daemon.json file.

{
    "dns": ["8.8.8.8"]
}

This is ok for me

or your ping command again.

still failed update, maybe something with my docker environment
