# This is an update script for gitea installed via the binary distribution
# from dl.gitea.io on linux as systemd service. It performs a backup and updates
# Gitea in place.
# NOTE: This adds the GPG Signing Key of the Gitea maintainers to the keyring.
# Depends on: bash, curl, xz, sha256sum, gpg. optionally jq.
# Usage: [environment vars] upgrade.sh [version]
# See section below for available environment vars.
# When no version is specified, updates to the latest release.
# Examples:
# upgrade.sh 1.15.10
# giteahome=/opt/gitea giteaconf=$giteahome/app.ini upgrade.sh
# apply variables from environment
