How to install a package?

To install a package using the apt package manager on a Debian-based Linux system (like Ubuntu), follow these steps:

1. Open a terminal.

2. Update the package lists to ensure you have the latest information about available packages:

   sudo apt update

3. Install the desired package using the following command:

   sudo apt install package-name

   Replace package-name with the name of the package you want to install.

4. Verify the installation (optional) by checking the version of the installed package:

   package-name --version

   Replace package-name with the actual command for the installed package, if applicable.
