He everyone, I am trying to install rancherOS from iso and I am getting the following error while running rancheros-install command: sudo rancheros-install -c cloud-config.yaml -d /dev/sda No install type specified…defaulting to generic All data will be wiped from this device Partition: true DEVICE: /dev/sda Are you sure you want to continue? [yN]yUnable to find image ‘rancher/os:v0.3.3’ locally Pulling repository rancher/os Get [https://index.docker.io/v1/repositories/rancher/os/images:](https://index.docker.io/v1/repositories/rancher/os/images:) dial tcp: lookup [index.docker.io](http://index.docker.io) on 8.8.4.4:53: dial udp 8.8.4.4:53: network is unreachable When I try to ping 8.8.8.8 I am getting network is unreachable. Is there any type of firewall running that I need stop? ---

Can you share a bit more about your deployment? If 8.8.8.8 or 8.8.4.4. are not reachable that typically means you don’t have networking conifgured. If you run `ip addr show` do you see an address configured? Did DHCP work? ---

It appears that the issue was related to DNS resolution [:53] and things are working w/o any issue at the moment. Thanks for all help! ---
