Hello I've just updated Drupal (to version 7.53) and now in Drush when I try launch the commands: "drush @theflyingeye.org up" (to update my website) or "drush @theflyingeye.org cc" (to clean chache) or "drush @theflyingeye.org dl view" (to download a basic module, view for example) I can just get this answer: "Unknown engine type outputformat"

If I digit:

"drush status" (after "su aegir")
I can get: 
"PHP configuration     :  /etc/php5/cli/php.ini                                 
 Drush version         :  5.10.0                                                
 Drush configuration   :  /var/aegir/.drush/drushrc.php                         
 Drush alias files     :  /var/aegir/.drush/server_master.alias.drushrc.php     
                          /var/aegir/.drush/theflyingeye.org.alias.drushrc.php  
                          /var/aegir/.drush/server_localhost.alias.drushrc.php

Do you have any advise please to fix this problem?

    Drush 5.10 is ancient so you should really, really upgrade. What does drush --debug version report? The "Unknown engine type outputformat" error indicates that you have another Drush around ...

  • Sort of looks like you have a contrib module that has a Drush extension that is using a feature not available in Drush 5.10. Try upgrading as suggested by others.

  • Thank you. I would like to specify the original installation is with AEGIR. Do you know if there is any special trick to update Drush through Aegir ?

  • The 'manual' upgrade script does it like this pretty much like the Drush docs suggest it.
