Recovering from manual git manipulations

[rigasml]

I read that we weren't supposed to do manual git operations -- the automatic nbgitpuller was working and then I think I did something manually to my repo or local clone and messed it up and cannot recover. I now cannot seem to get anything but this message no matter what I do when I use the nbgitpuller link.

$ git fetch

Figured out this issue by restarting Jupyter server and cleaning some environments
