Provide detailed info about your installation, including links to non-openSUSE URLs (and often for openSUSE stuff, too). I don’t see Official fish documentation, just aux documentation from outside the main project. Even official documentation can sometimes conflict with itself, so it’s important for others to evaluate not just the actions you did but how it’s supposed to fit into however the documentation/guide describes.
You need to descrbe source of your application, if it’s installed from openSUSE or somewhere else and possibly how you installed… by a supplied RPM, build from source, etc.
