I create a repository named test on http://localhost/gitstack/, now I can push some refs to ’http://localhost/test.git’, but when i edit the update.sample file under the C:\GitStack\repositories\test.git\hooks to update, there will be a error: remote: error: hook declined to update refs/heads/master. I want to invoke some scripts by update, but it is error now, so can you tell me how to deal with this problem, thank you very much.
