[Linux/Ubuntu 16.04 LTS] rmadison, devscripts 설치

🎈 서론

패키지를 설치하다 보면 가끔.. 보단 자주 Package <어쩌구> has no installation candidate 라는 경고문을 만나본 적이 있을 것이다. 아래와 같은 거..

root@user-desktop:~/Downloads# apt-get install libminizip1
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package libminizip1 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'libminizip1' has no installation candidate

rmadison을 사용해서 진짜 이 패키지를 설치할 수 없는 환경인지 알아보도록 하자!

🔨 설치

먼저 rmadison을 사용하기 위해선 devscripts를 설치해야 한다.

그 후, rmadison을 이용해서 패키지에 대한 상세한 정보를 볼 수 있다.

Ubuntu 16.04 LTS는 xenial이니 그 부분을 보면 된다.
