WatchTower bootloader is not supported on your OS, you'd have to run it manually
for the time being. Support for many editors and many OSes is planned for the
future, if you would like to help, or drop in an issue please don't hesitate to
do so on the project's Github page: https://github.com/TechnoGate/watch_tower
