몇 대의 데비안 lenny 컴퓨터가 있습니다. 두 파일은 거의 동일한 sources.list 파일을 가지고 있습니다. 둘 다 정기적 인 업데이트 / 안전 업그레이드를 수행합니다. 하나는 항상 부드럽게 진행됩니다. 다른 한편으로, 나는 다음과 같은 것을 얻습니다 :

말할 것도없이, 나는 진행하지 않는다. 무슨 일 이니? 어떻게 수정합니까? 다음은이 컴퓨터의 sources.list에있는 주석이 아닌 행입니다.

deb ftp://ftp.debian.org/debian/ lenny main contrib non-free
deb-src ftp://ftp.debian.org/debian/ lenny main contrib
deb http://security.debian.org/ lenny/updates main contrib non-free

고맙습니다.
