Error

The authenticity of host 'github.com (140.82.113.4)' can't be established.

Fix

ssh-keyscan github.com >> ~/.ssh/known_hosts

Example (eg. using CircleCI workflow)

- run:
    name: Add github.com to known hosts
    command: ssh-keyscan github.com >> ~/.ssh/known_hosts

User beware: doing this method above leaves you vulnerable to man-in-the-middle attacks. Instead, I'd recommend following GitHub's documentation on Testing your SSH connection. Pay special attention to the step where they ask you to compare the fingerprint returned in command line with GitHub's public fingerprint.

This worked for me, note that it automatically added 'github.com' to the list of known hosts
