title: git - fatal: Unknown index entry format
body: <p>When I'm trying use <code>git status</code> or <code>git checkout master</code> or <code>git pull</code>, </p>
  
  <p>I'm getting an <strong>error</strong> :- </p>
  
  <blockquote>
    <p>"fatal: Unknown index entry format 61740000".</p>
  </blockquote>
  
  <p>I've tried to Reinitialize existing Git repository. But it did not fix the problem.</p>
  
  <p>I'm new to git, and I have just made a first branch and make some changes and trying to commit the changes.</p>
  
  <p>Tried searching on Google but can't find the right solution for the code <strong>61740000</strong>.</p>
  
  <p>Edit: Deleted the whole local repository and then again cloned from remote repository (git status worked), created a branch (git status worked) and made changes to files (git status error).</p>
  
  <p>Please help.</p>
