I followed the railscasts and with basic configurations
such as image_id: ami-3f32ac3e (Ubuntu Server 12.04.3 LTS 64 bit), app_name: myapp, app_user: jashwant , I tried to deploy with rubber.
Everything went smooth. I now have a running instance, but at the end I am getting
Trying to enable root login

You can see the error here
I concluded from here that, I need to set :initial_ssh_user in config/deploy.rb
I already saw,
set :user, 'root'
set :password, nil
in config/deploy.rb
So, I added set :initial_ssh_user, 'ubuntu'. But the error remains the same.
If I change set :user, 'root' to set :user, 'ubuntu', then I get

Things I have checked after googling:
It's not happening because Amazon instance is still starting. I have waited long after the instance has started. Also, I get the same error when I do ALIAS=production cap rubber:refresh
I am able to successfully log in to this new instance via ssh (providing username as ubuntu ). So, key file is okay.
I have already added the key with ssh-add
Key file in .ec2 directory does not have .pem extension.
I do not have duplicate entries in my etc/hosts on Amazon instance.
It turned out that rubber wasn't able to read from private key. I fixed that and it worked.
