Unable to resolve host
I changed localhost to another more descriptive and now I get a message from sudo telling me the name or service is not known. Everything seems to be working except this message which is a little annoying. How can I resolve so this message disappears?

Patient: Doc…it hurts when I do this…
Doctor: Don't do that!
Just because you can do something doesn't mean that you should… localhost is a canonical name that has been used since Al Gore invented the internet ;-) Most network-aware programs take the fact that localhost is a synonym for the loopback address for granted. You should undo what you did.
If you want another, more descriptive name for 127.0.0.1 and ::1, just invent a new one, put it in your /etc/hosts file under the definition for localhost and start using it. Leave localhost the way it is!
