Ubuntu apt-get install에서 install-info 처리 중 에러 발생 시 해결법

OS: Ubuntu 16.04 (amd64)

새로 설치한 지 얼마 안된 우분투 16.04 머신에서 원래 잘 되던 패키지 설치(apt-get install)가 갑자기 진행이 안되면서 아래와 같이 install-info 를 processing하는 동안 에러가 발생했다는 메세지를 내뱉었다.

아래 출력은 openmpi 관련된 패키지를 설치하려고 시도하면서 발생한 에러를 그대로 가져온 것이다.

skylit@ns3sim:~$ sudo apt-get install libopenmpi1.10 libopenmpi-dev openmpi-common openmpi-bin

skylit@ns3sim:~$

SuperUser에 찾아보니 /etc/environment 파일을 아래와 같이 고치면 해결된다고 한다.

/etc/environment 파일:

LC_ALL="en_US.UTF-8"

실제로 내가 /etc/environment 파일을 열어 보니, LC와 ALL 사이, 그리고 en과 US 사이가 밑줄이 아니라 공백으로 되어 있었다. (LC ALL="en US.UTF-8") 

그런데 나는 해당 파일을 전혀 손댄 적이 없었고, 처음에는 이것저것 패키지 설치가 잘 되었던 기억이 나는데, 도대체 어떻게 고쳐진 것일까? ;;
