Do you have "PubkeyAuthentication yes" in your /etc/ssh/sshd_config file
on your remote host?  It should be there by default if you're using
Ubuntu on it.

Also, just out of curiosity, did you set a password on your ssh key?
When creating your ssh key it prompts for an *optional* password.  If
you entered one in at the prompts, that might be the password it's
asking for.  If you did provide a password when creating your ssh keys,
and don't want to use a password with them, you'll have to re-generate
your keys and just hit 'Return/Enter' at the password prompts.  This
will create a set of keys that don't require a password.
