apt-get -f 설치에 실패하면 어떻게 해야 합니까? [폐쇄]

내 상황은 매우 어렵습니다.

Debian Jessie/Stretch에서 실패했습니다 apt-get -f install.

시스템이 효과적으로 정체되었습니다. 지금 SSH가 있습니다. 로그인 터미널에 관한 한 하나만 사용할 수 있습니다. (즉, alt-ctrl-F1만 실제 시스템에 로그인 터미널을 불러왔고, alt-ctrl-f[2-5]는 실패했습니다).

나열된 오류와 관련된 것 같습니다.여기. 하지만 몇 가지 문제가 있습니다. PolicyKit 시간 초과에 도달했기 때문에 krb-kdc가 압축을 풀지 못하고 (g-io-error-quark, 24), LDAP가 활성화되어야 한다는 오류 메시지와 함께 krb5-admin-server의 압축을 풀 때 오류가 발생합니다(활성화되어 있고 연결이 괜찮습니다).

즉, apt-get에는 여러 시간 초과가 있습니다(PolicyKit 비트의 경우인 것 같습니다). 네트워크의 경우 타임아웃을 1200으로 설정했는데 별 효과가 없는 것 같습니다. 전체 오류 메시지:

질문:

1. 강제로 또 무엇을 할 수 있나요 apt-get -f install?
2. Jessie에게 롤백을 강제하면 도움이 될까요?
