wget https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

i got the message below:

ERROR: cannot verify raw.githubusercontent.com's certificate, issued by "XXXXX"

It just because i can't use https in terminal, it not related to the k8s certificate

Resolving raw.githubusercontent.com (raw.githubusercontent.com)... 127.0.0.1 You are trying to connect to localhost

Please check what you have in your /etc/resolve.conf . The issue looks like the issue with your local certifiacte. Ihave just attempted to reproduce it and confirm it's working as expected. I'm able downloading that file.

wget https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
