Failure to auth with public key against GitHub while vanilla git works correctly.

In Des's case, the issue was that the SSH keys hadn't been added to the SSH agent.

I do this by running this command in my .zshrc:

ssh-add --apple-load-keychain

For @timamehro61, the issue was a combination of:

1. SSH keys not being added to the agent.
2. Had generated an SSH key using ssh-keygen with default options, which creates an RSA + SHA-1 key, which something was refusing to use because it was insecure.

We solved 2. by getting Tima to generate a new SSH key using ed25519 as per the GitHub guide's recommendations.

We then solved 1. by adding these lines to .ssh/config, then cloning a repo once via vanilla git to trigger the new SSH key to be added to the agent:

UseKeychain yes
AddKeysToAgent yes

@james I think those 2 SSH config lines are possibly a replacement for running ssh-add --apple-load-keychain.

Thanks all, I will close this. Please feel free to ask me on Slack or create issues in this repo if you have any further issues with Grit.

The same error can also present when using something like 1Password as your SSH agent. In that case you need to set the SSH_AUTH_SOCK environment variable like so: https://github.com/ezzatron/dotfiles/blob/994de384e49ad9305e05c48eb606626d25b05c94/dotfiles/.zshenv#L42

@jmalloc I was thinking maybe we should have a small troubleshooting guide for Grit somewhere with all of these common issues. Any thoughts? Preferences on a wiki page vs. something in the repo?

I don't use wikis, something in the repo would be cool.
