I had to add my new rsa identity in my machine!

So, first of all I created a new rsa key:

ssh-keygen -t rsa -C "my_name@gmail.com" -f ~/.ssh/id_rsa_heroku

then added to my machine

ssh-add ~/.ssh/id_rsa_heroku

and, finally, to Heroku

heroku keys:add ~/.ssh/id_rsa_heroku.pub

After that,

git push heroku master
