unable to locate package dconf-tools

I've been following the instructions for the awesome live build:
https://www.kali.org/docs/developmen...ng-live-build/

I'm running the Kali virtual box VM.

The issue:
Everything goes fine till I run the ./build.sh -v.
This runs fine for a while grabbing all the files, etc and then I get the following error:

unable to locate package Nessus
and
unable to locate package dconf-tools

Note I've downloaded the nessus deb file as instructed and moved it to the suggested location.

Code:

~/live-build-config/kali-config/common/packages.chroot/Nessus-8.10.1-debian6_amd64.deb

The log:

Solutions I've tried:
Running another apt update and using a different build variant.
both result in the same error.

I've also tried the solution suggested on the archives here:
https://forums.kali.org/showthread.p...kage-not-found

after changing my source file to the following:

Code:

# Kali-Rolling is the main user distro deb [arch=i386,amd64,armel,armhf,arm64] https://http.kali.org/kali kali-rolling main contrib non-free deb [arch=i386,amd64,armel,armhf,arm64] https://http.kali.org/kali kali-rolling main/debian-installer deb-src https://http.kali.org/kali kali-rolling main contrib non-free

I ran an apt update and tried again.
yet it still results in the same error.

Anyone able to shine some light on this?:confused:
