Git – Cannot push to Heroku because key fingerprint

gitgit-pushherokussh

I am new to Rails, and I was trying to deploy a very simple app to Heroku. This is the second app that I deploy, and the first one I was able to do it just fine. However I am having some issues with this one. Whenever I "git push heroku master", I get this error:

! Your key with fingerprint xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx is not authorized to >access my_heroku_app.

fatal: The remote end hung up unexpectedly

I have tried to manage my keys after logging in heroku. If I type in my console "heroku keys", then I get:

No keys for myemailaddress.

However, If I run the comand "heroku keys:add" I get

Found existing public key: /Users/michele/.ssh/id_rsa.pub
Uploading ssh public key /Users/michele/.ssh/id_rsa.pub
! Fingerprint already exists. Please use one ssh key per Heroku account

Please help me! This is soo frustating, I have no idea what's wrong!
Thank you

I had the same problem, I followed this post and others of the same kind without success :-((

Finally, I found the solution: 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 "giordano.scalzo[at]gmail.com" -f  ~/.ssh/id_rsa_heroku

then added it 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

worked like a charm!

Hope this helps.
