Start by reading 1-install-dependencies.sh and checking the package and repository setup plus DNS reachability on Ubuntu 24.04 arm64. Reproduce on a Raspberry Pi 5; done means dependency installation completes for the Docker packages and pigz, with the reported package-resolution failures understood or handled.
