Pop-OS 배포판과 함께 제공되는 기본 저장소를 얻는 방법은 무엇입니까?

내부 파일을 삭제했는데 /etc/apt/sources.list.d파일에 아무것도 없습니다 /etc/apt/sources.list. apt배포판을 설치했을 때의 상태로 되돌리고 싶습니다 . 환매 계약 등.

어떤 리포지토리가 필수적이며 이를 내 sources.list파일과 sources.list.d폴더에 어떻게 추가합니까?

실행할 때 오류가 발생합니다.sudo add-apt-repository "deb http://apt.pop-os.org/proprietary $(lsb_release -cs) main"
