Apt repository for the Taghub public display (Raspberry Pi / Debian arm64). The taghub-display package installs this same configuration itself, so this is only needed to install the first time with apt instead of a downloaded .deb:
sudo curl -fsSL https://apt.taghub.io/taghub-archive-keyring.gpg -o /usr/share/keyrings/taghub-archive-keyring.gpg printf 'Types: deb\nURIs: https://apt.taghub.io/\nSuites: stable\nComponents: main\nSigned-By: /usr/share/keyrings/taghub-archive-keyring.gpg\n' | sudo tee /etc/apt/sources.list.d/taghub-display.sources sudo apt update && sudo apt install taghub-display
Suites: stable (releases) and candidate (releases and release candidates, for test devices).
