title: How to resolve git's "not something we can merge" error
body: <p>I just encountered a problem when merging a branch into master in git. First, I got the branch name by running <code>git ls-remote</code>. Let's call that branch "branch-name". I then ran <code>git merge branch-name</code> command and got the following result:</p>
  
  <pre><code>fatal: branch-name - not something we can merge
  </code></pre>
  
  <p>How do I resolve this error?</p>
