Bcm2710-rpi-3-b-plus.dtb bug

Taking backup of bcm2710-rpi-3-b-plus.dtb.
Installing new bcm2710-rpi-3-b-plus.dtb.
ln: failed to create symbolic link '/boot/dtb-': Operation not permitted
dpkg: error processing package flash-kernel (--configure):
installed flash-kernel package post-installation script subprocess returned error exit status 1

This is the error message with this package. This fails all bundled packages. The isssue is the /boot/dtb- does not exit. What does exist is /boot/dbt-1. This package needs help.
