I ran into a bit of trouble uploading an app to heroku for the first time, I was unable to authenticate.
root@chris-VirtualBox:~/site# git push heroku master Permission denied (publickey). fatal: The remote end hung up unexpectedly
This turned out to be an issue with my public key, in order to fix it simply create a new one:
root@chris-VirtualBox:~/site# ssh-keygen -t rsa Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: ...
Re-upload it:
root@chris-VirtualBox:~/site# heroku keys:add /root/.ssh/id_rsa.pub Uploading ssh public key /root/.ssh/id_rsa.pub
And finally re-push everything:
root@chris-VirtualBox:~/site# git push heroku master Enter passphrase for key '/root/.ssh/id_rsa': Counting objects: 579, done. Compressing objects: 100% (513/513), done. Writing objects: 100% (579/579), 6.09 MiB | 83 KiB/s, done. Total 579 (delta 101), reused 0 (delta 0) -----> Heroku receiving push -----> Ruby/Rails app detected
