title: Conda takes 20+ minutes to solve environment when package is already installed
body: <p>NOTE:
  I'm duplicating this post because the question has been up on the conda github page for ~6-days with no response.  The original link is here:

  <h2>Current Behavior</h2>
  
  <p>When I type try to run <code>conda update -n base conda</code>, conda hung for around 20-minutes on 'Solving environment' and then returned a package plan that did not include an updated version of conda.  The package plan that was returned is provided below.  </p>
  
  <p><strong>The package plan that was returned is as follows:</strong></p>

  <p>NOTE: the conda version I have installed is 4.5.11 - I'm not sure if this is the most recent version and haven't been able to find a command or resource (other than <code>conda update conda</code>) to check what the most recent version is.  I also had a similar problem when trying to <code>conda install websocket-client</code> when websocket client was already installed - I wonder if the current version of conda has trouble when the most recent version of a package is already installed.</p>
  
  <p>NOTE 2: <code>conda update --all</code> solved the environment in a reasonable amount of time (~1 min - I didn't time it precisely).</p>
  
  <h3>Steps to Reproduce</h3>
  
  <p><code>
  conda update -n base conda
  </code></p>
  
  <p>As I mentioned above, <code>conda install websocket-client</code> also hung at 'Solving environment' - I already had websocket-client version 0.53.0 installed when I tried to run the install command</p>
  
  <h2>Expected Behavior</h2>
  
  <p>Conda should either:
  1. If the most recent version is installed, conda should promptly inform the user that an update isn't needed.
  1. If a newer version is available, I'd expect Conda to solve the environment in a shorter period of time. I think that less than 1-2 minutes would be reasonable - 20+ minutes is too long</p>
