Yes, but he's testing it on the local machine as well....

What has gotten me in the past is the permissions on the .ssh folder istself.
They should be 744 I believe.

There is a command to add keys to a remote server as well that's
rarely mentioned.
I don't have my Ubuntu box in front of me, but I'm pretty sure it's
  ssh-copy-id or at least ssh-copy-something
where `ssh-copy-id -i path/to/public/key remoteuser at remotehost` will
copy the key to the right place with the right permissions.

Also, when testing ssh, if you use a couple of -v then troubleshooting
is much easier.
  ssh -v
