-# 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
-current_version=$(cat manifest.json | jq -j '.version|split("~")[0]')
-# Some jq magic is needed, because the latest upstream release is not always the latest version (e.g. security patches for older versions)
-version=$(curl --silent "https://framagit.org/api/v4/projects/20125/releases" | jq -r '.[] | select( .tag_name | contains("rc") or contains("beta") | not ) | .tag_name' | sort -V | tail -1)
-assets=($(curl --silent "https://framagit.org/api/v4/projects/20125/releases" | jq -r '[ .[] | select(.tag_name=="'$version'").assets.links[].url ] | join(" ") | @sh' | tr -d "'"))
-
-# Later down the script, we assume the version has only digits and dots
-# Sometimes the release name starts with a "v", so let's filter it out.
-# You may need more tweaks here if the upstream repository has different naming conventions. 
-if [[ ${version:0:1} == "v" || ${version:0:1} == "V" ]]; then
-    version=${version:1}
-fi
-
-# Setting up the environment variables

-# For the time being, let's assume the script will fail
-echo "PROCEED=false" >> $GITHUB_ENV
-
-# Proceed only if the retrieved version is greater than the current one
-if ! dpkg --compare-versions "$current_version" "lt" "$version" ; then
-    echo "::warning ::No new version available"
-    exit 0
-# Proceed only if a PR for this new version does not already exist
-elif git ls-remote -q --exit-code --heads https://github.com/$GITHUB_REPOSITORY.git ci-auto-update-v$version ; then

-fi
-
-# Each release can hold multiple assets (e.g. binaries for different architectures, source code, etc.)
-echo "${#assets[@]} available asset(s)"
-
-#=================================================
-# UPDATE SOURCE FILES
-#=================================================
-
-# Here we use the $assets variable to get the resources published in the upstream release.
-# Here is an example for Grav, it has to be adapted in accordance with how the upstream releases look like.
-
-# Let's loop over the array of assets URLs
-for asset_url in ${assets[@]}; do
