Authentication Failure on Github even after adding SSH key

Question

I get fatal:Authenication Failure when I try to push code to my repo. I've added the public key on my github account as well. When I do : ssh -i [email protected]
I get Hi amangupta052! You've successfully authenticated, but GitHub does not provide shell access.

Can anyone help? Thanks

That depends on the remote url you have used.

If git remote -v returns:

https://github.com/username/reponame

Then your ssh setup won't matter. But this would work:

ssh://[email protected]:username/reponame

Another cause is linked to your private key: if it is pass-phrase protected, with a special character in it, that usually don't work well.
See here for other ssh causes of failure.

To replace your remote named origin, use git remote commands:

git remote set-url origin ssh://[email protected]:username/reponame

(as explained in the GitHub help page about changing the rmeote url)

If you see::

ssh: Could not resolve hostname github.com:amangupta052: 
     Name or service not known 
fatal: The remote end hung up unexpectedly

Try the non-scp ssh syntax:

git remote set-url origin ssh://[email protected]/username/reponame

(note the '/' instead of the ':' after github.com)

Maybe this would have worked, as commented in this blog post:

git remote set-url origin [email protected]:username/reponame

(scp-like syntax, but without the ssh:// prefix)

As I mention here, an scp syntax usually means an ~/.ssh/config file to work properly.
