title: How can I get unstuck from CondaUpgradeError "A newer version of conda is required."?
body: <p>I attempted to downgrade my conda version.  With conda at version 4.6.2, I ran <code>conda install conda=4.5.12</code>.  I then went to run other conda commands, but was met with the following error:</p>
  
  <pre><code>CondaUpgradeError: This environment has previously been operated on by a conda version that's newer
  than the conda currently being used. A newer version of conda is required.
    target environment location: /home/selah/anaconda3
    current conda version: 4.5.12
    minimum conda version: 4.6
  </code></pre>
  
  <p>I am now stuck and unable to successfully run any conda commands.  How can I get conda back in working order again?</p>
