나는 이것을 시도했지만 성공하지 못했습니다. 이 문제를 어떻게 해결할 수 있나요?

답변1

명령 apt-get install --reinstall앞에 sudo가 없습니다 .

다음과 같은 명령sudo x && y 오직x다음 명령을 실행하십시오 . sudo이 y명령은 일반 사용자 권한으로 실행됩니다.

따라서 해당 구문을 사용하려면 그렇게 해야 합니다 sudo x && sudo y.

답변2

Kali Linux에서 다음 중 하나를 사용하여 사용할 수 있습니다.

sudo apt-get update && sudo apt-get upgrade -y

답변3

매우 늦었다는 것을 알고 있지만 sudo su 실행하려는 명령을 입력하고 다시 시도하는 것이 더 쉽습니다.
