-#=================================================
-# 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=$(cat manifest.json | jq -j '.version|split("~")[0]')
-repo=$(cat manifest.json | jq -j '.upstream.code|split("https://github.com/")[1]')
-# Some jq magic is needed, because the latest upstream release is not always the latest version (e.g. security patches for older versions)
-version=$(curl --silent "https://api.github.com/repos/$repo/releases" | jq -r '.[] | select( .prerelease != true ) | .tag_name' | sort -V | tail -1)
-
-# 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
-echo "Current version: $current_version"
-echo "Latest release from upstream: $version"
-echo "VERSION=$version" >> $GITHUB_ENV
-echo "REPO=$repo" >> $GITHUB_ENV
-# 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$version ; then
-    echo "::warning ::A branch already exists for this update"
-    exit 0
-fi
-
-#=================================================
-# SPECIFIC UPDATE STEPS
-#=================================================
-
-# Any action on the app's source code can be done.
-# The GitHub Action workflow takes care of committing all changes after this script ends.
-
-#=================================================
-# GENERIC FINALIZATION
-#=================================================
-
-# Replace new version in manifest
-echo "$(jq -s --indent 4 ".[] | .version = \"$version~ynh1\"" manifest.json)" > manifest.json
-
-# No need to update the README, yunohost-bot takes care of it
-
-# The Action will proceed only if the PROCEED environment variable is set to true
-echo "PROCEED=true" >> $GITHUB_ENV
