Git push error: Unable to unlink old (Permission denied)

Question

In the remote server I have a post-receive hook set up in order to make a git checkout of my repository:

#!/bin/sh
GIT_WORK_TREE=/var/www/ git         


        

Answer 1

I get this error, and other strange git errors, when I have a server running (in Intellij). Stopping the server and re-trying the git command frequently fixes it for me.
