stoke/scripts/install-apt.sh

#!/usr/bin/env bash
#
# One-time setup to install stoke via apt on Debian/Ubuntu.
#
# Adds the heavy-duty Forgejo Debian registry as an APT source (with its
# signing key) and installs the stoke package. Safe to re-run; afterwards
# stoke upgrades through regular `apt-get upgrade`.
#
# Usage:
#   ./scripts/install-apt.sh
#   FORGE_URL=... OWNER=... ./scripts/install-apt.sh   # non-default instance
#
# Run as root or as a user with sudo.
