Network seems to be there, since the pin test(s) succeeded. But DNS resolution seems to not work. Can you check this manually:

getent hosts dns9.quad9.net
getent hosts dietpi.com

If it fails, please check your DNS nameserver entries:

cat /etc/resolv.conf

I tried adding the manual entries in the resolv.conf, and then the dietpi is able to ping and get the results

however the moment i run the dietpi-update, the resolv.conf gets reset only to 127.0.0.1 for nameserver dns

curl: (6) Could not resolve host: raw.githubusercontent.com

nameserver 127.0.0.1

Are you using Pi-hole, AdGuard Home, Unbound or some other local DNS resolver? It seems to not work. It is generally no good idea to use a DNS resolver for its own host system. Better use a public DNS, like the upstream DNS nameserver used by your local resolver directly. Ad blocking is not required for a server system.

cktechie2012 commented 5 months ago

I tried adding the manual entries in the resolv.conf, and then the dietpi is able to ping and get the results

however the moment i run the dietpi-update, the resolv.conf gets reset only to 127.0.0.1 for nameserver dns

MichaIng commented 5 months ago

Is some software controlling the content?

realpath /etc/resolv.conf
cktechie2012 commented 5 months ago

this is the output

dietpi@DietPi:~$ realpath /etc/resolv.conf
/run/systemd/resolve/resolv.conf
dietpi@DietPi:~$

Not using any tool like pihole or adguard

cktechie2012 commented 5 months ago

This is the output

dietpi@DietPi:$ realpath /etc/resolv.conf
/run/systemd/resolve/resolv.conf
dietpi@DietPi:$

Not using any tool like pihole or adguard

MichaIng commented 5 months ago

systemd-resolved. If you did not install/use this intentionally, get rid of it:

G_SUDO G_AGP systemd-resolved
sudo rm -f /etc/resolv.conf
echo 'nameserver 1.1.1.1' | sudo tee /etc/resolv.conf
getent hosts dietpi.com

If you for whatever reason need to use it, you need to configure it to use a proper upstream DNS.

PSA: don't upgrade now if you're on Armbian bookworm, as they are having issues with their apt repo: https://github.com/armbian/build/issues/6762

I'm not sure if this is related to OP's issue but I figured people running into this will look at this issue first.

MichaIng commented 5 months ago

Thanks for the heads up. Next release will remove the Armbian repository from DietPi systems, so those kind of issues will then be gone, as long as we do not cause such with our own APT repo 🙂.
