I just launched DreamCompute and installed Ubuntu 16.04. My instance is called “Home”. I’m following a tutorial and added a new user called “testuser”
However, when I open Putty up and try logging into the server using “testuser”, I get an error: Server Refused Our Key. I’m using the same key that I use for my admin “ubuntu” user, which logs in fine.
How can I set it up like Dreamhost does, so I can login through Putty using different usernames?
When I do various commands in the shell as the admin user, for example: “sudo adduser testuser” , I keep getting the same error: “sudo: unable to resolve host home”, even though the command still works. How do I fix this?
