Ubuntu에서 apt-get을 사용하여 충족되지 않은 종속성 해결

나는 기계 작업을 하고 있어요 Ubuntu 12.04.2 LTS (GNU/Linux 3.5.0-43-generic x86_64). 다른 프로젝트와 함께 프로덕션 환경에서 실행되는 서버이기 때문에 매우 주의가 필요합니다.

특정 프로그램 목록을 설치해야 했기 때문에 먼저 일반적인 프로그램을 실행한 apt-get update후 다음 명령을 계속 실행했습니다.

apt-get install python-dev libxslt1-dev libpq-dev git python-pip nginx supervisor wget libxml2-dev mongodb build-essential libxslt1-dev libxrender1 libxext6`

이것이 내가 얻는 것입니다:

root@SERVERLINUX:~# apt-get install python-dev libxslt1-dev libpq-dev git python-pip nginx supervisor wget libxml2-dev mongodb build-essential libxslt1-dev libxrender1 libxext6

git is already the newest version.
python-pip is already the newest version.
build-essential is already the newest version.
libxext6 is already the newest version.
libxrender1 is already the newest version.
libxrender1 set to manually installed.
python-dev is already the newest version.
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 libpq-dev : Depends: libpq5 (= 9.1.14-0ubuntu0.12.04) but 9.1.9-0ubuntu12.04 is to be installed
             Depends: libkrb5-dev but it is not going to be installed
             Depends: comerr-dev but it is not going to be installed
 libxml2-dev : Depends: libxml2 (= 2.7.8.dfsg-5.1ubuntu4.9) but 2.7.8.dfsg-5.1ubuntu4.6 is to be installed
 linux-image-generic-lts-quantal : Depends: linux-image-3.5.0-44-generic but it is not going to be installed
 mongodb : Depends: mongodb-server but it is not going to be installed
           Depends: mongodb-dev but it is not going to be installed
 nginx : Depends: nginx-full but it is not going to be installed or
                  nginx-light but it is not going to be installed
 supervisor : Depends: python-medusa (>= 0.5.4) but it is not going to be installed
              Depends: python-meld3 but it is not going to be installed
              Depends: python-support (>= 0.90.0) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

"충족되지 않은 종속성"이 있는 패키지를 설치하려면 어떻게 해야 합니까? 이러한 종속성을 어떻게 충족할 수 있나요? -f제안된 대로 이 옵션을 사용하는 것은 모든 것을 망칠 수 있기 때문에 두렵습니다 .
