When I attempt to git pull origin [branch] in order to pull in changes

  • 0

When I attempt to git pull origin [branch] in order to pull in changes to the repo, I am prompted for a password. My system password and just hitting enter return: “fatal: Authentication failed”.

The thing is, I never entered a password for this project in the past and this was not the case when I began it last week, nor any of the times I pushed and pulled since then. Speaking to my client, they thought it was something with my SSH keys.

I double checked the keys and made sure they were correct, running ssh git@github.com. I’m getting:

Hi bdkay! You’ve successfully authenticated, but GitHub does not provide shell access.
Connection to github.com closed.

which makes me think it succeeded. However, right before that a troublesome line reading: “PTY allocation request failed on channel 0” occurs. The client says I’m still added to the repo in github and they have not changed anything on their end. I’m still working on the same machine but cannot seem to find a fix through google or searching this site. Any help is greatly appreciated.

    If you’re being prompted for a password, and not your SSH key’s passphrase, then you’re not using the SSH URL. HTTPS asks for user/pass auth, SSH uses key/passphrase. Check your remote’s URL with git remote -v, and if you need to fix it use git remote set-url.
