我正在我的 Linux Mint (cinnamon) PC 上使用 gnuplot 和 Rust 来完成一个项目。然而，一旦我尝试显示图片，我就会得到：
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)
这看起来没问题，因为我还没有下载 Gnuplot。然而一旦我跑了
sudo apt install gnuplot
我明白了
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
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
我不知道我现在应该做什么。感谢任何帮助，谢谢
编辑：我已经跑了
apt update

答案1
您的存储库设置缺少安装软件包所需的主 Ubuntu 存储库。查找包含jammy-security（可能是/etc/apt/sources.list.d/official-package-repositories.list）的文件：
grep -rl jammy-security /etc/apt/sources.list*
编辑它，使其包含以下行：
deb http://packages.linuxmint.com victoria main upstream import backport
deb http://archive.ubuntu.com/ubuntu jammy main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu jammy-updates main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu jammy-backports main restricted universe multiverse
deb http://security.ubuntu.com/ubuntu/ jammy-security main restricted universe multiverse
然后使用 进行更新sudo apt update，您应该能够安装该gnuplot包及其依赖项。
