# This is an update script for forgejo installed via the binary distribution
# from codeberg.org/forgejo/forgejo on linux as systemd service. It
# performs a backup and updates Forgejo in place.
# NOTE: This adds the GPG Signing Key of the Forgejo maintainers to the keyring.
# Depends on: bash, curl, xz, sha256sum. optionally jq, gpg
# See section below for available environment vars.
# When no version is specified, updates to the latest release.
# Examples:
# upgrade.sh 1.15.10
# forgejohome=/opt/forgejo forgejoconf=$forgejohome/app.ini upgrade.sh
# Check if forgejo service is running
