Struggling to trigger FileNotFound Error in get_github_auth()

[lwasser]

I can't figure out how to trigger the filenotfound error in the get_github_auth() function.

see discussion here:

I just haven't been able to trigger it no matter what i try so i'd like to talk that through. i can revisit it later but it's an issue impacting pr #462

I think that this particular check is not necessary. It was written to catch the case where a user does not have a openssh installed. Instead, the installation instructions should be clear about what system dependencies are needed and we should not check for these in the code (i.e. we don't check that someone has git installed).
