패키지를 설치하려고 할 때 apt는 종속성 제거에 대해 불평하고 다음을 실행하도록 제안합니다 apt --fix-broken install.
# apt install vim
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
libpam-modules : PreDepends: libpam-modules-bin (= 1.4.0-11ubuntu2) but 1.4.0-11ubuntu2.1 is to be installed
vim : Depends: vim-runtime (= 2:8.2.3995-1ubuntu2.3) but it is not going to be installed
Depends: libsodium23 (>= 1.0.14) but it is not going to be installed
하지만 실행하면 항상 불법 명령과 코어 덤프가 발생합니다.

흥미롭게도 일부 다른 프로그램도 작동하지 않아 Illegal Instruction 오류가 발생합니다. 예를 들면 다음과 같습니다.

인터넷에서 해결책을 찾아보았으나 정보가 거의 없습니다. 사람들이 "불법 명령"을 보는 모든 경우는 잘못 컴파일한 코드를 실행하려고 할 때입니다(예: 잘못된 CPU 아키텍처를 대상으로 함). 하지만 여기서는 공용 Ubuntu 저장소에서 제공하는 일부 바이너리를 일반적인 Intel CPU에서 실행하려고 합니다. 무슨 일이야? 손상된 파일 시스템에서 이러한 유형의 오류(예: 물리적 디스크 손상)가 발생할 수 있습니까? 아니면 CPU와 관련된 건가요?
