title: git rebase getting invalid upstream
body: <p>I did the following:</p>
  
  <p><strong>git fetch --all</strong></p>
  
  <p><strong>git checkout -b my-feature-branch master</strong> </p>
  
  <p>// did some edits</p>
  
  <p><strong>git commit -m "some commit comments"</strong></p>
  
  <p><strong>git rebase another-branch</strong></p>
  
  <p>I get git error: "invalid upstream 'another-branch'</p>
  
  <p>I can see the 'another-branch' on the remote so I am not sure what is happening. Any help is really appreciated.</p>
