title: Cron jobs are not working on EC2 Aws Ubuntu 18.04 instance?
body: <p>How you doing?</p>
  <p>I've been trying desperately these days to achieve to run a script each 6 hours without any success, I even tried the simpliest scripts and they don't trigger at any moment, I dont know what Im doing wrong.</p>
  <p>First I tried to add a new crontab using <code>crontab -e</code>, adding the following line:
  <code>1 * * * * root echo &quot;test&quot; &gt; /home/ubuntu/test.txt</code></p>
  <p>This cron job should be executed each minute and override the contect with the string &quot;test&quot;, but neither it does create the file or adds the string (obviously)</p>
  <p>I've also tried modifying the /etc/crontab file, without any success, there I've added the following line:
  <code>* * * * * root date &amp;&amp; echo 'it works' &gt;&gt; /home/ubuntu/crontest.log 2&gt;&amp;1</code></p>
  <p>With the same result, never it gets executed, the service is running, I made apt updates and everything and nothing seems to work, why?</p>
