I am using gnuplot and Rust for a project on my Linux Mint (cinnamon) PC. However once I try to display a picture I get:

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)

This seems ok as I haven't downloaded Gnuplot. However once i run

sudo apt install gnuplot

I get

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

and I have no idea what I should do now. Any help is apreciated, thanks

EDIT: I already ran

apt update

and apt policy returns

Your repository setup is missing the main Ubuntu repository needed to install packages. Look for the file containing jammy-security (it’s probably /etc/apt/sources.list.d/official-package-repositories.list):

grep -rl jammy-security /etc/apt/sources.list*

Edit it so that it contains these lines:

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

Then update with sudo apt update, and you should be able to install the gnuplot package and its dependencies.
