Old post but I came up with this problem today, ended up googling and had found myself here. I had figured it out on my own but thought I'd share my issue & solution in my case to help out anyone else who may have the same issue.

Issue:

[root@centos [username]]# ssh-keygen -t rsa

Enter file in which to save the key (/root/.ssh/id_rsa):I HAD JUST HIT ENTER

/usr/bin/ssh-copy-id: ERROR: No identities found

Solution:

Enter file in which to save the key (/root/.ssh/id_rsa): **/home/[username]/id_rsa**

Be sure if you are doing this as root you are coping the key into the user directory you wish to login with. NOT the root user directory.

I was sshing into the machine when performing this operation, so I guess ssh-copy-id just point to the dir you are logged in as by default.

Hope this helps anyone.
