Debian Buster 운영 체제 및 소프트웨어 패키지를 새로 설치한 후: command-not-found

실행 명령:

$ curl
Could not find the database of available applications, run update-command-not-found as root to fix this

루트로 게시해도 update-command-not-found문제가 해결되지 않습니다. 버그 리포트가 있지만 아직 수정되지 않은 것 같습니다.

# curl

Command 'curl' not found, but can be installed with:

apt install curl

추신. 궁금한 분들을 위해 말씀드리자면 새로 설치 시 데이터베이스가 누락되었기 때문입니다.

ls -l /var/lib/command-not-found
total 0

그 후 apt update우리는:

ls -l /var/lib/command-not-found
total 2504
-rw-r--r-- 1 root root 2560000 Jul 29 12:34 commands.db
-rw-r--r-- 1 root root     983 Jul 29 12:34 commands.db.metadata

답변2

변경 권한은 다음 위치에 있습니다.

sudo chmod o+r /var/lib/command-not-found/commands.db*

하지만 그 전에

권한 변수 상태 정보 확인

ls -l /var/lib/command-not-found

total 2588

-rw-r----- 1 root root 2834432 Dec 18 05:25 commands.db
-rw-r----- 1 root root    4712 Dec 18 05:25 commands.db.metadata

그것은해야한다:

ls -l /var/lib/command-not-found

total 2588

-rw-r--r-- 1 root root 2641920 Jan 16 00:27 commands.db
-rw-r--r-- 1 root root    1175 Jan 16 00:27 commands.db.metadata
