title: Error in installing a conda package
body: <p>I'm trying to install a conda package(macs2). I've installed conda and, to make sure it is installed, I typed: </p>
  
  <pre><code>conda list
  </code></pre>
  
  <p>I got installed packages, so conda is installed. </p>
  
  <p>Then I tried this command to install macs2:</p>
  
  <pre><code>conda create --name macs macs2
  </code></pre>
  
  <p>And here is the error:</p>
  
  <pre><code>PackageNotFoundError: Package not found: '' Package missing in current linux-64 channels: 
    - macs2
  
  You can search for packages on anaconda.org with
  
      anaconda search -t conda macs2
  </code></pre>
  
  <p>I have Ubuntu 64.</p>
