apt-get 업데이트 실패: 다음 서명이 유효하지 않습니다.

최근에 내 노트북(Ubuntu 12.04)에서 업데이트를 확인하려고 했으나 확인에 실패했습니다.

sudo apt-get update:

이 문제를 해결하는 방법을 잘 모르겠으며 조언을 주시면 감사하겠습니다.

답변1

좀 더 검색한 끝에 발견한해결책.

오류와 관련된 파일을 삭제/이름 바꾸기:

cd /var/lib/apt/lists/partial/
sudo mv us.archive.ubuntu.com_ubuntu_dists_precise_main_i18n_Index main_COPY
sudo mv us.archive.ubuntu.com_ubuntu_dists_precise_multiverse_i18n_Index multi_COPY
sudo mv us.archive.ubuntu.com_ubuntu_dists_precise_restricted_i18n_Index res_COPY
sudo mv us.archive.ubuntu.com_ubuntu_dists_precise_universe_i18n_Index uni_COPY

서명 업데이트:

gpg --keyserver keyserver.ubuntu.com --recv 40976EAF437D05B5

소프트웨어 캐시 재구축:

cd /var/lib/apt
sudo mv lists lists.old
sudo mkdir -p lists/partial
sudo apt-get update

목록을 이동하는 것만으로도 첫 번째 단계를 건너뛸 수 있지만, 오류를 제거하는 데 사용한 전체 과정을 설명하는 것이 가장 좋다고 생각했습니다.

답변2

새 키를 가져와 보세요.

gpg --keyserver keyserver.ubuntu.com --recv 40976EAF437D05B5
gpg --export --armor 40976EAF437D05B5 | sudo apt-key add -
