I have found out that myth curl was trying to send an IPv6 request... Which means that https://pkgs.k8s.io does not support IPv6 yet ?

Mean while, I had to do this to solve my issue.

echo 'ipv4' >> ~/.curlrc

@Martin-Luther Thank you for raising the issue. But here I had tried but it is not triggering such error. Can you Please check Which Ubuntu and deb you are using if you are using older than Debian 12 and Ubuntu 22.04, then you manually need to make directory using sudo mkdir -p -m 755 /etc/apt/keyrings before executing this command. Here i think the error is due to the restriction to use the directory so above command will help you to make directory with access.

If you satisfied all these criteria and still you are facing an issue then check if your network might have a firewall or proxy that is blocking the request so disable it.

else check whether you entered the correct url.

The issue was solved by forcing curl, apt-get & wget to use ipv4 because my system is ipv6 by default.

/retitle https://pkgs.k8s.io/ does not support ipv6

moving this to k8s.io for triage, seems like the ipv6 problem should be checked /transfer k8s.io

Hello, After more investigations, it seems like my provider gave me IPv6 addresses that were blocked by GCP. So I could only use IPv4. I have tried with another provider, and things worked just fine with IPv6. Let's say that someone in the same situation finds this ticket; is it possible to say to Kubeadmn, Kubelet & Kubectl to fallback to IPv4 when IPv6 fails ?

@Martin-Luther What cloud provider are you using? We have been observing blocked IP addresses from Hetzner; are you using Hetzner by any chance?

As mentioned in my previous message :

I am @ Gandi, and seriously thinking about moving to Digital Ocean or Hostinger if they allow me o add additional volumes ...
