"debconf - 통신 덤프 코어". QUIT("Signal 3")을 보내는 것은 무엇입니까?

(이미 설치했어요 systemd-coredump)

QUIT무엇에게 신호를 보내야 할까요 debconf-communicate?

역추적에 /가 포함되어 있지 않기 때문에 이 치명적인 신호가 raise()다른 실행 중인 프로그램에 의해 kill()전송 되었다고 가정할 수 있습니까?debconf-communicate

man 7 signal신호가 QUIT원래 "키보드에서 나가기" 위해 사용되었다고 말합니다. 신호("키보드 인터럽트")와의 차이점은 코어가 의도적으로 덤프된다는 INT것입니다 . QUIT아마도 이것은 디버깅 기술인 것 같습니다. SIGINTCtrl+C 키 조합을 통해 보냅니다. SIGQUITCtrl+\를 통해 보냅니다.

apt그러나 터미널에서 실행 중인 명령에서 Ctrl+\를 누르는 사람이 없어도 이러한 코어 덤프를 얻는 것 같습니다. 패키지 업그레이드를 위해 PackageKit을 사용할 때 이런 일이 발생하는 것 같습니다(가끔?).

이것은 Debian 9 데스크탑 시스템(GNOME)입니다. 이 충돌이 발생하면 사용자가 어떤 문제도 보고하지 않았다는 것 외에는 무엇을 기대해야 할지 모르겠습니다 :-). 기본 사용자는 일반적으로 업데이트 적용에 능숙하고 업데이트의 중요성을 이해합니다.

과거에 업데이트 알림을 보내지 못했던 데비안의 버그로 인해 시스템은 현재 일반적인 pk-update-icon..desktopgnome-packagekitgpk-update-viewergnome-software
