title: Packet tracer 7.2.2 close on login
body: <p>when i try to login on packet tracer after putting my mail the program closes and this shows on my terminal.</p>
  
  <pre><code>:~$ sudo packettracer  
  Starting Packet Tracer 7.2.2
  /usr/local/bin/packettracer: línea 8:  3352 Excepción de coma flotante   (`core' generado) ./PacketTracer7 "$@" &gt; /dev/null 2&gt;&amp;1
  :~$ 
  </code></pre>
  
  <p>the error in spanish says something like : line 8: 3352 Floating point exception ( 'core' generated)</p>
  
  <p>I had to install a packet tracer on a newly installed ubuntu 18.04.3 I followed <a href="https://linuxhint.com/install_packet_tracer_ubuntu_1804/" rel="nofollow noreferrer">this</a> guide, with the exception that instead of .tar.gz I had to download the PacketTracer-7.2.2-ubuntu-setup.run, it has to be the version 7.2.2. I had it installed and working until recently that I had to format my computer.
  Also if I close the login window I can see that the UI it's loaded but since I didn't log in it closes.</p>
  
  <p>additional information:</p>
  
  <pre><code>:~$cat /var/log/syslog
