title: Ubuntu terminal starts with the Anaconda base environment (how to correct that?)
body: <p>I have downloaded and installed the Anaconda distribution for Ubuntu (18.04) from [<a href="https://www.anaconda.com/distribution/#download-section]" rel="noreferrer">https://www.anaconda.com/distribution/#download-section]</a> conform instructions some weeks ago. Everything worked fine.</p>
  
  <p>Today I updated the packages in the Gnome terminal with:</p>
  
  <pre><code>source activate base
  conda update --all --yes
  conda deactivate
  exit
  </code></pre>
  
  <p>Before I did this update, my terminal started with:</p>
  
  <pre><code>rene@mylaptop:~$
  </code></pre>
  
  <p>After the update a terminal session starts as follows (with the Anaconda base environment activated):</p>
  
  <pre><code>(base) rene@mylaptop:~$ 
  </code></pre>
  
  <p>How can I prevent this from happening / revert to the previous terminal settings?
  Any suggestions?</p>
