호환성 문제로 이전 버전의 gcc와 g++(4.6.3)를 설치해 보았는데 지금은 apt가 망가진 것 같습니다. apt-get install은 dpkg뿐만 아니라 모든 것에 대해 이 작업을 수행하는 것 같습니다.

gcc 4.6.3을 설치하려고 할 때 구성 스크립트를 실행했는데 아마도 --target 옵션에 잘못된 값을 제공했을 것입니다. 나는 성공하지 못한 채 다음과 같은 다양한 조합을 시도했습니다.
apt-get update && apt-get upgrade
apt-get install -f
sudo dpkg --configure -a
apt-get remove/purge/autoremove gcc
또한 Synaptic은 손상된 포장이 없다고 주장합니다.
제안해 주셔서 감사합니다.

The following packages are only half configured, probably due to problems
configuring them the first time. The configuration should be retried using
dpkg --configure <package> or the configure menu option in dselect:
gcc GNU C compiler
종속성에 대한 불만과 함께 다음 중 하나를 제거하려고 하면 실패합니다.
