Update failed message

I get the following when trying to update CR Pro from 3.8 to 3.9.3: Notice: Undefined index: package in /usr/home/ucwadmin/public_html/wp-admin/includes/class-theme-upgrader.php on line 378 Updating Theme Catch Responsive Pro (1/1) An error occurred while updating Catch Responsive Pro: Update package not available. Note: I do have a child theme active, in case that might have an effect.
