title: git fetch not fetching a remote branch on a fresh clone on Red Hat Enterprise Linux Server 7.7 (Maipo)
body: <p>On RedHat server 7.7</p>
  <p>I ran the following commands.</p>
  <pre><code>git clone https://github.com/postgres/postgres.git
  cd postgres
  git remote add upstream https://github.com/postgres/postgres.git
  git fetch upstream REL_12_STABLE
  </code></pre>
  <p>The output was as follows:</p>
  <pre><code>From https://github.com/postgres/postgres
   * branch            REL_12_STABLE -&gt; FETCH_HEAD
  </code></pre>
  <p>instead of</p>
  <pre><code>From https://github.com/postgres/postgres
  * branch REL_12_STABLE -&gt; FETCH_HEAD
  * [new branch] REL_12_STABLE -&gt; upstream/REL_12_STABLE
  </code></pre>
  <p>If i run the git branch –r command, we DO NOT see an extra upstream/REL_12_STABLE entry</p>
  <p>While on RedHat 8 every thing works fine.</p>
