dpkg error 해결 방법 dpkg: warning: not found in PATH or not executable

결과적으로 말하면 위의 error시에는 두가지 문제가 있을 수있다.

1.  /etc/sudors 랑 echo $PATH로 확인했을때 PATH가 잘못되었거나 

2. not found 된 명령어가 없거나

 

나의 경우 2번째 문제였다.

 

이번에 nginx를 좀 공부하면서 nginx lua 기능을  사용해보려 했다...

nginx-extras 명령얼를 사용하니 아래와 같은 패키지가 종속성에 걸려서 재설치 하려 했다....

apt-get install nginx-extras

E: Unable to correct problems, you have held broken packages.

바로 apt-get update ; apt-get upgradeapt-get --with-new-pkgs upgrade 명령어를 날렸으나 위의 libc6 패키지는 kept back라서수동으로설치해야 할듯 했다...

apt-get install libc6

여기서 부터 이상했다 Yes, do as I say!를 입력하라고 한 순간부터 불안했지만 어차피  docker 니까 라는 생각에 go 했다.

 

그리고 그뒤부터 apt install 관련 명령어는 다 고장났다 ;;;;

뭘 인스톨 하던간에 아래와 같은 내용 나오면서 중단되었다. 보니까 PATH에 저 세개가 없다는 것 같은데....

perl: warning: Setting locale failed.

	LC_ALL = (unset),
	LANG = "en_US.UTF-8"
    are supported and installed on your system.

dpkg: warning: 'ldconfig' not found in PATH or not executable
dpkg: error: 1 expected program not found in PATH or not executable
Note: root's PATH should usually contain /usr/local/sbin, /usr/sbin and /sbin

 

근데 /etc/sudores에 가면 path는 잘되어있다...

root유저에서 echo $PATH를 해봐도 원하는 path 모두 있다,....

vi /etc/sudores

Defaults        env_reset
Defaults        mail_badpass
Defaults        secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin"

 

path가 정상이면 path에서 원하는게 없다는 건데 다시 잘 읽어보니

Can't exec "locale": No such file or directory at /usr/share/perl5/Debconf/Encodingg.pm line16.

dpkg: warning: 'ldconfig' not found in PATH or not executable

두개 명령어를 실행해야하는데 명령어가 없나보다. 잘찾아보니 

askubuntu.com/questions/847615/perl-warning-falling-back-to-the-standard-locale-c

에서 

Both /usr/bin/locale and /sbin/ldconfig are in package libc-bin. Install that package to fix your errors.

 

란 힌트를 얻을 수 있었다. 

lib-bin을 설치해주면 될것 같은데 문제는 dpkg가 안되서 수동설치해야한다.

아래를 따라한다. 

mkdir /tmp/lib-bin-files
cd /tmp/lib-bin-files

apt-get update
apt-get download lib-bin

ar -x libc-bin_*.deb

tar -xf data.tar.xz
cp ./usr/bin/locale /usr/bin
cp ./sbin/ldconfig /sbin

이렇게 해주면 끝! 다시 정상 작동한다!
