Ошибка в Ubuntu 20.04 LTS && система не может найти пакет pi-bluetooth

Я новичок в Ubuntu и хотел бы установить pi-bluetooth для своих проектов, но не могу. Я просмотрел несколько форумов, но не получил точного ответа на свой конкретный запрос. Я использую Ubuntu 20.04.2 LTS в подсистеме Windows для Linux (WSL). Когда я использую команду sudo apt update && sudo apt upgrade, я получаю:
