An Introduction To The Apt Package Manager

Hello all! My name is Dan, and I post tech tutorials and news!

1. Installing packages

Installing a package with Apt is pretty straightforward. First, you need the package name. Let’s use “sl” as an example. sl is a small Linux package that prints a moving steam locomotive across the screen when you type “sl” in the terminal. One thing to always remember. In most cases, unless you are logged in as “root”, you will need to type “sudo” before such a command, because it requires administrator privileges. With this information, to install a package, you need to type the following command:

sudo apt install sl

It should output something similar to this:

If it asks you if you wish to continue, press Y on your keyboard. Otherwise, if the output is similar to this, congratulations! You’ve successfully installed your first package with Apt! Type “sl” and press Enter to watch the steam locomotive go by. Choo choo!

Tip

Install multiple packages at once by adding a space between each package name.

2. Uninstalling packages

Uninstalling packages is just as easy as installing them. Instead of “install”, you simply replace it with “remove”. Let’s use our “sl” package from earlier as an example.

sudo apt remove sl

Your output should look something like this:

As before, if it asks you if you wish to continue, press Y on your keyboard. Otherwise, if the output is similar to this, congratulations! You’ve successfully removed a package with Apt!

3. Updating packages

With Apt, updating is a simple process, and it updates all installed packages at once. Simply run this command:

sudo apt full-upgrade

I won’t attach an image here because depending on how m any packages you have installed, the output can get quite lengthy. However, it will most likely ask for confirmation, so press Y on your keyboard when prompted. full-upgrade checks all mirrors for the latest version of each package and installs it if the mirror’s version number is higher than your system’s.
