노트:이 질문이 중복된 것 같아요"E: 패키지 ''에는 설치 후보가 없습니다.", 하지만 이 질문에 유일하게 게시된 답변은 나에게 전혀 도움이 되지 않았습니다. 나는 댓글과 답변에 있는 각 제안의 결과를 포함하여 질문보다 더 많은 정보를 포함하려고 노력했습니다.
배경:저는 Raspbian Wheezy를 실행하는 Raspberry Pi 1 Model B를 가지고 있는데, 이전에 ROS(로봇 운영 체제)를 설치했지만 다른 작업은 별로 하지 않았습니다. 이번 주에는 소스에서 몇 가지 추가 ROS 패키지를 설치하려고 했습니다. 다양한 컴파일러 및 종속성 문제를 해결하려고 시도하는 동안(인정합니다. 인터넷에서 임의의 명령을 실행하는 데 문제가 있었습니다. 문제는 libboost를 업그레이드한 다음 이전 버전으로 되돌리려고 시도한 후에 시작되었습니다.) 분명히 성공했습니다. apt-get시스템을 완전히 플러시합니다 .
내 문제는 apt-get더 이상 아무 것도 성공적으로 설치할 수 없다는 것입니다. 내가 시도한 모든 것은 "E: 패키지 '패키지 이름'에 설치 후보가 없습니다." 오류로 끝납니다(예, sudo apt-get update이 오류를 계속해서 반복해서 실행했습니다.source.list의 여러 변형). 및 에 따르면 apt-get upgrade모든 것이 최신 상태입니다 apt-get dist-upgrade. aptitude물건을 설치하는 데 더 이상 도움이 되지 않습니다.
기존 설치를 복구하고 싶지만 많은 작업 없이 시스템을 복구할 수 없는 경우 새 이미지에서 재부팅할 의향이 있습니다. 중요한 모든 것을 백업해 두었습니다.
다음은 /etc/apt/ 디렉터리에 있는 모든 .list 파일의 내용입니다.
