Не удалось запустить apache2.service: Единица apache2.service не найденный

Я просто установил xampp в своей человечности 16.04, и теперь мой сервер не работает. Если я выполняю эту команду для запуска апача sudo systemctl start apache2 Я получаю эту ошибку Failed to start apache2.service: Unit apache2.service not found. Другая проблема состоит в том, когда я работаю php -v Я получаю это сообщение

Я не мог найти решение до сих пор. Было бы хорошо, если кто-то мог бы помочь мне.
