@minherz ah, I see the problem…

The code expects the “compact” form of the .ssh key

id-rsa <base64encoded> <user@server>

This is a legit bug in the code. For now, you can work around it by transforming your key to match that form using:

 ssh-keygen -i -f existing_key.pub > formatted_key.pub

Very new to all of this. Can anyone tell me how I use ssh-keygen -i -f existing_key.pub > formatted_key.pub?

I don’t understand the work around. I am very new to all of this and trying to follow a tutorial on aks and they didn’t have this problem.
