title: Is it safe to run "conda update anaconda" if some packages will be downgraded or removed?
body: <p>This is the output when I run <code>conda update anaconda</code>.</p>
  
  <pre><code>The following packages will be downloaded:
  
      package                    |            build
      ---------------------------|-----------------
      python-slugify-1.2.6       |             py_0           6 KB  conda-forge
      ------------------------------------------------------------
                                             Total:           6 KB
  
  The following packages will be REMOVED:
  
    text-unidecode-1.2-py_0
  
  The following packages will be DOWNGRADED:
  
    python-slugify                                 3.0.3-py_0 --&gt; 1.2.6-py_0
  </code></pre>
  
  <p>In the past, I never see packages going to be removed and/or downgraded when I run this command. Should I proceed if some packages will be downgraded or removed? But if I don't proceed, how am I going to update anaconda packages in future?</p>
  
  <p>I am running python v3.7 on Windows 10.</p>
