GitHub Clone Error: Cannot clone with EOF error

Question

I am trying to clone my project from GitHub private repo using Ubuntu 13.04.

I am getting error as below all the time

error: RPC failed; result=18, H         


        

Answer 1

First check if the issue persists, because there were some issues this morning with GitHub.
See its status history:

Today
6:52 UTC Everything operating normally.
6:50 UTC Some GitHub pages are again unavailable. We are continuing to investigate. 

If it does persists, check also if you can reproduce it on different computer/OS.
As shown in this issue, if this really is because of some huge content, then test it with a shallow clone.
