# PACKAGE UPDATING HELPER
#=================================================
# This script is meant to be run by GitHub Actions
# The YunoHost-Apps organisation offers a template Action to run this script periodically
# Since each app is different, maintainers can adapt its contents so as to perform
# automatic actions when a new upstream release is detected.
#=================================================
# FETCHING LATEST RELEASE AND ITS ASSETS
#=================================================
# Fetching information
