title: Cosmos installation fails
body: <p>I'm trying to install locally cosmos.</p>
  
  <p>I followed the guide instructions and successfully execute puppet script on slave machines.
  I've a problem executing puppet script on the master machine.</p>
  
  <p>The script fails. Here is the content of puppet.err log file:</p>
  
  <pre><code>[1;31mError: /Stage[main]/Cosmos::Setup/Exec[cosmos-setup]: Failed to call refresh: /opt/pdi-cosmos/cosmos-admin/cosmos-admin setup returned 255 instead of one of [0][0m
  [1;31mError: /Stage[main]/Cosmos::Setup/Exec[cosmos-setup]: /opt/pdi-cosmos/cosmos-admin/cosmos-admin setup returned 255 instead of one of [0][0m    
  </code></pre>
  
  <p><strong>EDIT</strong></p>
  
  <p>This is the output running manually <code>cosmos-admin setup</code></p>
