For new installation of 8.16.2, post-receive hooks are not working and so mail notifications and activities logs are not showing on dashboard. This is the error we are getting while push to the repo

This is the post-receive hook file

#!/opt/gitlab/embedded/bin/ruby

Fix the PATH so that gitlab-shell can find git-upload-pack and friends.

ENV[‘PATH’] = ‘/opt/gitlab/bin:/opt/gitlab/embedded/bin:’ + ENV[‘PATH’]

#!/usr/bin/env ruby
