Git push origin master having publickey issues

Question

I'm having some trouble committing a default rails app to git, and I've hit a wall in troubleshooting the problem. I am currently running Ubuntu 11.10. I am running git version 1.7.5.4. I ran through the series of

git init
git add .
git commit -m "first commit"
git remote add origin git@github.com:username/first_app.git
git push -u origin master

I also make the repo on github.com, but then I get this error:

Permission denied (publickey).
fatal: The remote end hung up unexpectedly

Thoughts?

You need to add the public key of your system to the git admin interface on github.com.
