방금 Stretch에서 Buster로 업그레이드했는데 apache2와 ssh 서비스 모두 시작 시 로드가 지연되고 어떤 경우에는 로그인하거나 수동으로 시작해야 작동합니다. mariadb나 시작 시 실행되는 다른 서비스에는 문제가 없습니다. 이는 터미널 전용이며 데스크톱 환경이 설치되어 있지 않습니다. 어떻게 되어가나요?
또한 처음에 Apache와 SSH를 설치하지 않고 Stretch를 새로 설치하려고 시도한 다음 Buster로 업그레이드하고 Apache와 SSH를 설치했는데 모든 것이 예상대로 작동했습니다.
여기서 "나쁜 시스템"의 저널actl에서 내보낸 로그의 일부를 볼 수 있습니다.

답변1
문제가 해결되었습니다. 댓글에 @AB님이 링크한 글을 읽었습니다. 로그인하면 crng init가 완료될 때까지 멈춥니다.
나는 같은 문제가 있다는 것을 발견했습니다. "손상된 시스템"과 "새로 설치된 시스템" 사이의 커널 버전을 확인한 결과 서로 다른 것을 발견했습니다. 나는 명령을 외친다업데이트가 용이함그리고 커널, 아파치, SSH를 포함해 업그레이드 가능한 소프트웨어 패키지가 많이 있습니다. 업데이트 후에는 모든 것이 정상으로 돌아왔습니다.
