Dear,  
  
  
  
When I type the command:  
  
php app/console mautic:update:find --env=prod  
  
I get following error:  
  
[2015-03-10 19:31:35] mautic.ERROR: An error occurred while attempting to fetch updates: Unknown cipher in list: TLSv1 [] []  
  
An error occurred while checking for updates. Please try again later.  
  
  
  
Kind Regards,

Hi Nick,

Manually replace the UpdateHelper.php file mentioned in the 1.0 announcement then try again. It should take care of that.

Thanks!
