gnuplot을 설치할 수 없습니다

저는 Linux Mint(계피) PC에서 gnuplot과 Rust를 사용하여 프로젝트를 진행하고 있습니다. 그러나 이미지를 표시하려고 하면 다음과 같은 결과가 나타납니다.

called `Result::unwrap()` on an `Err` value: Couldn't spawn gnuplot. Make sure it is installed and available in PATH.
Cause: No such file or directory (os error 2) 

아직 Gnuplot을 다운로드하지 않았기 때문에 괜찮은 것 같습니다. 하지만 일단 도망치면

sudo apt install gnuplot

알겠어요

Package gnuplot-x11 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

나는 지금 무엇을 해야할지 모르겠습니다. 도움을 주셔서 감사합니다. 감사합니다.

편집 : 나는 달렸다

apt update

그리고 적절한 정책 반환
