Getting this error when running on a fresh new install of Debian 7 on DigitalOcean node

class { 'nginx': }

or ($::operatingsystem == 'debian' and $::operatingsystemmajrelease in ['6', '7']) { $_module_os_overrides = { 'manage_repo' => true, 'daemon_user' => 'www-data', }
I presume operatingsystemmajrelease is undefined for some reason. Deleted that line and it worked great

@sangm which version of Facter are you using? If it's the one packaged by Debian it would be 1.6.10 while this module requires 1.7.0 or higher.

operatingsystemmajrelease fact was added in 1.7.0.

I'm closing this for now. @sangm please comment if you have any information to add and I'll reopen. Thanks!
