Open a Terminal:

Update Package Lists:

It's a good practice to start by updating the package lists to ensure you have the latest information about available packages:

sudo apt update

Install Ruby:

You can install Ruby by running the following command:

sudo apt install ruby-full

This command will install the full Ruby package along with its development tools.

Verify Installation: After the installation is complete, you can verify it by checking the Ruby version:

ruby --version

This will display the installed Ruby version.

Optional - Install Bundler:

Bundler is a package manager for managing Ruby gems. You can install it with the following command:

sudo gem install bundler

This step is optional but can be helpful for managing dependencies in Ruby projects.
