changes not reflecting at git server

Question

I have installed Git and configured it as server in CentOS and Windows as client machine.

And then I made one repo and tried to push changes but failed with error <

Answer 1

Make sure that:

• your server has git 2.3+

• you have set on that server:

   git config --global receive.denyCurrentBranch updateInstead
  

(See "Push to a non-bare Git repository")

Make sure first that your repo on the server is not a bare repo.
