Q:

Failed to push some refs to GitHub

I created a new GitHub repository. On my first time trying git push origin master, I get this mystifying error:
remote: /usr/lib/ruby/1.8/pathname.rb:441:in `lstat': No such file or directory - /data/repositories/b/nw/ba/91/bin (Errno::ENOENT)
remote:     from /usr/lib/ruby/1.8/pathname.rb:441:in `realpath_rec'
remote:     from /usr/lib/ruby/1.8/pathname.rb:474:in `realpath'
remote:     from -e:1
To https://github.com/backseatviolist/lilysmufl
 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'https://github.com/backseatviolist/lilysmufl'

How do I fix this?

A:

Since it is an error on the remote side (GitHub), it should be linked to some issue GitHub is having those last few hours.
See GitHub Status history

Some Pages sites for users that use apex domains are currently unavailable. We're working to resolve the problem as quickliy [sic] as possible.

Check if the issue persists (and if it does contact the GitHub support)
Note: for the very first push, try a:
git push -u origin master

See "Why do I need to explicitly push a new branch?".

The OP ColdFusion actually comments:

Something went wrong during the creation of the repository;
  GitHub support suggested I delete it and try again.
  Issue resolved
