Rubik Pi 3 V02 Ubuntu 24.04.2 LTS: Upgrade fails

the update script recommended here fails:
https://www.thundercomm.com/rubik-pi-3/en/docs/rubik-pi-3-user-manual/1.0.0-u/Update-Software/3.1.upgrade-ubuntu

git clone -b ubuntu_setup --single-branch GitHub - rubikpi-ai/rubikpi-script: Scripts that may be used during development with RUBIK Pi.

cd rubikpi-script

it works until here

But when I start the shell script:
./install_ppa_pkgs.sh

I get the follwing errors:

E: Unable to locate package xwayland
E: Unable to locate package ffmpeg
E: Unable to locate package net-tools
E: Package ‘pulseaudio-utils’ has no installation candidate
E: Unable to locate package python3-pip
E: Unable to locate package selinux-utils
E: Unable to locate package unzip
E: Unable to locate package v4l-utils

I tried the following:

apt --fix-broken install

rerun ./install_ppa_pkgs.sh (no change)

Does your Rubik Pi 3 have a working network connection?
We recommend reflashing the image with the official Qualcomm Launcher; this will provide you with the latest software revision and should allow you to proceed more smoothly.
