Permission denied (publickey) when deploying herok

Question

I'm attempting to deploy my code to heroku with the following command line:

git push heroku master

but get the following error:

Permission denied (publickey).
fatal: The remote end hung up unexpectedly

I have already uploaded my public SSH key, but it still comes up with this error.

Answer 1

The problem I faced was on Windows and invariably whenever I run the "heroku keys:add" it selected the github keys. So here are the steps I followed to resolve the issue

1. went to the .ssh directory under "Document and Settings" folder and deleted the git hub keys
2. run the command heroku keys:add

The above command asked me to generate a new keys and following was the output Could not find an existing public key. Would you like to generate one? [Yn] Y Generating new SSH public key. Uploading SSH public key C:/Documents and Settings/Admin/.ssh/id_rsa.pub... done ! The 'heroku' gem has been deprecated and replaced with the Heroku Toolbelt, download and install from https://toolbelt.heroku.com.

1. rerun the command heroku keys:add

The above command will not give the following output Found existing public key: C:/Documents and Settings/Admin/.ssh/id_rsa.pub Uploading SSH public key C:/Documents and Settings/Admin/.ssh/id_rsa.pub... done

1. Now use the git push heroku master

for me using the above steps solved the issue and was able to deploy the application on the cloud.

Answer 2

I have this issue as well. I am using Mac OSX. The way I fixed that was to login as admin

sudo su

password

Answer 3

This was the solution for me:

ssh-add ~/.ssh/my_heroku_key_rsa

Answer 4

If you've already uploaded the key then try to remove the key and then re-upload it with a new key.

 heroku keys:remove //removes the existing key
 ssh-keygen -t rsa //generates a new key in ~/.ssh folder
 heroku keys:add    //uploads the new key, if no arguments r passed then the key generated                              
                    //in default directroy i.e., ~/.ssh/id_rsa is uploaded
 git push heroku

this should work.

Answer 5

I had this problem when TortoiseGIT was installed on my machine. After changing the environment variable GIT_SSH from

"c:\Program Files\TortoiseGit\bin\TortoisePlink.exe"

to

"c:\Program Files (x86)\Git\bin\ssh.exe"

and following this tutorial with ssh-keygen and keys:add, it works!

Answer 6

One single command works:

heroku keys:add

It will make one if it doesn't exist.
