kaltura-db-config.sh FAILED with: 255 on line 182

From my reading so far it appears to be an issue with the version of php that im running as there are several bug reports regarding this area of the process as well as talk about anything over php 5.5 so i assume this also has to do with my version which is

php -v
PHP 5.6.25 (cli) (built: Sep 3 2016 19:17:54)
Copyright (c) 1997-2016 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies

line 182 is

php $APP_DIR/deployment/base/scripts/installPlugins.php >> $LOG_DIR/installPlugins.log 2>&1

so im not sure what the issue is exactly with the 255 value and why its failing..

Here is the output from the installPlugins.log
