답변1

문제는 입력한 값이 /etc/hostname의 어떤 항목과도 ​​일치하지 않는다는 것입니다 /etc/hosts.

이로 인해 명령이 hostname --fqdn확인되지 않은 호스트 이름을 반환하여 ssmtp설치를 방해합니다.

컴퓨터의 호스트 이름을 /etc/hosts.

정말 끔찍해 보입니다.

hostname: Name or service not known
dpkg: error processing package ssmtp (--configure):
 subprocess installed post-installation script returned error exit status 1

hostname스크립트에 사용됩니다 postinst(데비안 패키지 유지관리자 가이드에 설명되어 있습니다 -협회)실패한.

버전 2.64-8(amd64)에 언급된 패키지를 확인하면 ssmtp다음 스크립트가 있습니다.

가장 중요한 것은:

hostname="${RET:-`hostname --fqdn`}"

언급했듯이 hostname --fqdn실패했습니다. 다음 사항을 확인하세요.

  • 명령이 존재합니다
  • hostname --fqdn어떤 명령이 반환됩니까?
