Failed to clone: authentication required but no callback set

[ghost]

Trying to clone a public github repository, but recieving the error 'failed to clone: authentication required but no callback set; class=Ssh (23)'
I am using just the HTTP url. no SSH involved.

` let url = "https://github.com/rust-lang/book";

let _ = match Repository::clone(url, path) {
    Ok(_) => {
        println!("cloned the book from github")
    }
    Err(e) => panic!("failed to clone: {}", e),
};

`

You may want to check if you have an insteadOf in your global git config.
