Permission denied (publickey). fatal: Could not read from remote repository

Question

I've read most of the related issues and tried most of the solutions but nothing has worked for me.

I have installed Rails and Git through RailsInstaller and I'm trying to upload my rails application into heroku from Windows 7 but I keep getting Permission denied (publickey) although my keys are uploaded into heroku.

Here is the log of how I've tried uploading my ssh keys the last time:

Please make sure you have the correct access rights
and the repository exists.

$ heroku keys

Can anyone see what I'm doing wrong or has any suggestions?

Update

Here are some more details on what log i get when i runshh on verbose

Solution

Make sure you only have /c/Users/firstname.lastname/.ssh your public and private keys id_rsa and id_rsa.pub (no id_dsa file)

Even if your key has been uploaded to heroku, double-check that heroku keys:add see your public keys (heroku key management), and recognized it already had been published on Heroku side. (And that it is the right one)

Make sure the environment variable HOME is set at all time to /c/Users/firstname.lastname in your git-bash session.

Make sure your ssh keys aren't passphrase protected (at first, for testing) and that you don't have an ssh agent which might get confused with the ssh key used: see "Unable to push git repo to Heroku, despite valid SSH keys".

you can also try and reset the keys.

SSH keys for a user should go into that user's home folder, not into a system-wide folder. As VonC pointed out in his answer, Git Bash will look for SSH keys in the user's home folder.
