title: Supervisor - Invalid user name
body: <p>I'm trying to run supervisor on Ubuntu 16.04. There was no problem in installation. I created file /etc/supervisor/conf.d/test.conf</p>
  
  <pre><code>[program:test]
  process_name=%(program_name)s_%(process_num)02d
  command=php /data/web/test.com/web/artisan queue:work --sleep=3 --tries=3 --daemon
  autostart=true
  autorestart=true
  user=forge
  numprocs=8
  redirect_stderr=true
  stdout_logfile=/data/web/test.com/web/storage/logs/workers.log
  </code></pre>
  
  <p>But when I run command</p>
  
  <pre><code>supervisorctl reread
  </code></pre>
  
  <p>I'm getting following error:</p>
  
  <p>ERROR: CANT_REREAD: Invalid user name forge in section 'program:test' (file: '/etc/supervisor/conf.d/test.conf')</p>
  
  <p>Any ideas what's wrong? Tried to search for solution but still not working...</p>
