Revise paste Install EOS Code editor

Elementary OS's default code editor (formerly known as Scratch, now simply called Code) is a lightweight, GTK-based editor tailored for the Pantheon desktop environment.
It's not available as a standard package in Linux Mint's repositories, and it's not distributed via Flatpak on Flathub or elementary's own Flatpak repo. The easiest and most reliable ways to install it on Linux Mint (which is Ubuntu-based) are:

1. Recommended: Install via the elementary OS Daily PPA
This provides pre-built .deb packages and is the simplest method, though note that the "daily" PPA builds from the latest development branch (potentially less stable than releases).

Run these commands in the terminal:

sudo apt update
sudo apt install software-properties-common
sudo add-apt-repository ppa:elementary-os/daily
sudo apt update
sudo apt install io.elementary.code

After installation, launch it by searching for "Code" in the menu or running io.elementary.code in the terminal.

To remove it later (if needed):

sudo apt remove io.elementary.code
sudo add-apt-repository -r ppa:elementary-os/daily
sudo apt update

There's also a "stable" PPA (ppa:elementary-os/stable), but it may not always have the latest version of Code.
