System Overview Error after Updating

Updated some modules and upon returning to the dashboard the system overview widget wasn't displaying and I recieved the following error in a red popup:
Whoops\Exception\ErrorException Call to undefined method Error::singleton() File:/var/www/html/admin/modules/dashboard/classes/phpsysinfo/includes/output/class.Output.inc.php:40

Any insight?
