title: anaconda navigator getting stuck at loading applications
body: <p>I have installed Anaconda on my Desktop running Ubuntu 18 Mate LTS. The output of</p>
  <pre><code>python --version
  </code></pre>
  <p>is</p>
  <pre><code>Python 3.6.5 :: Anaconda, Inc.
  </code></pre>
  <p>First of all, when I try to launch Anaconda Navigator using</p>
  <pre><code>anaconda-navigator 
  </code></pre>
  <p>the application gets stuck at Loading applications stage. I have to eventually kill this using <kbd>CTRL</kbd>+<kbd>C</kbd>/<kbd>CTRL</kbd>+<kbd>Z</kbd>. The anaconda navigator never launches.</p>
  <p>Following this, I tried</p>
  <pre><code>conda update anaconda-navigator
  </code></pre>
  <p>and</p>
  <pre><code>conda update conda
  </code></pre>
  <p>None of these commands work.</p>
  <p>I tried to look for the solution online and at one site, I was guided to use the following set of commands</p>
  <pre><code>source ~/anaconda*/bin/activate root
  anaconda-navigator
  </code></pre>
  <p>Even this did not work.
  It was showing some SSL Verification Failed message. The message was as follows:  -</p>
  <blockquote>
  <pre><code>CondaHTTPError: HTTP 000 CONNECTION FAILED for url &lt;https://repo.anaconda.com/pkgs/main/noarch/repodata.json.bz2&gt;
  Elapsed: -
  
  An HTTP error occurred when trying to retrieve this URL.
  HTTP errors are often intermittent, and a simple retry will get you on your way.
  
  If your current network has https://www.anaconda.com blocked, please file
  a support request with your network engineering team.

  <p>SSLError(MaxRetryError('HTTPSConnectionPool(host='repo.anaconda.com',
  port=443): Max retries exceeded with url:
  /pkgs/main/noarch/repodata.json.bz2 (Caused by SSLError(SSLError(&quot;bad
  handshake: Error([('SSL routines', 'ssl3_get_server_certificate',
  'certificate verify failed')],)&quot;,),))',),)</p>
  </blockquote>
  <p>Following this, I googled this problem and at one of the sites, the developers suggested me to use</p>
  <pre><code>conda config --set ssl_verify False
  </code></pre>
  <p>I did this. Then afterwards, I do not see the error message (obviously because ssl verify has been turned off). But then, instead of any error message, I keep on getting the following report at my terminal (no matter what conda command I use). The report looks something like this: -</p>

  <p>The interesting this is that the first time when I launched anaconda-navigator after installing it, navigator window did get launched. After that, I shut down my system after working and from then onward anaconda-navigator window would not launch. I am also not sure if this is due to internet connection or anaconda installation/configuration.</p>
  <p>Any suggestions ?</p>
