This guide will walk you through all the simple steps of installing apps on your Ubuntu machine like a pro. Let's get started!
Getting Started with Ubuntu Software Center
The Ubuntu Software Center is like the App Store, but for Ubuntu. It's the easiest way to find and install software without any command-line hassle.

Using the Terminal to Install Applications
For those who love a bit of adventure or prefer the classic way, using the terminal is as cool as it sounds!
- Open the Terminal: You can do this by pressing
Ctrl + Alt + T
or searching "Terminal" in your applications. - Install with APT: Most of the time, you’ll use the
sudo apt install <application-name>
command. Super simple! - Update Your Repositories: Always remember to run
sudo apt update
before installing anything. Keeps things fresh!
Installing Applications from DEB Packages
Sometimes, you’ll come across .deb files, which are like .exe files in Windows. Need to know how to install applications on Ubuntu using these? Here’s how:
- Download the DEB File: Get it from the official site of the software.
- Use the Terminal: Run
sudo dpkg -i /path/to/yourfile.deb
to install. - Fix Dependencies: If there are any missing dependencies, use
sudo apt install -f
.
Exploring Snap Packages for Quick Installs

- Check if Snap is Installed: Newer Ubuntu versions have it by default. Just run
snap
in the terminal to check. - Install a Snap Package: Use
sudo snap install <application-name>

Flatpak for Wider Application Access
Flatpak is another format like Snap, aimed at making applications easier to install and update.

flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
. - Install Apps: Use
flatpak install flathub com.spotify.Client
as an example command.
Adding PPA Repositories for Latest Software
Sometimes you need the very latest version of a software. Here's the trick:
- Add a PPA: Use
sudo add-apt-repository ppa:example/ppa
. - Update and Install: Don't forget to update first with
sudo apt update
and then install your app.
Installing from Source for the Brave
If you’re feeling adventurous and need cutting-edge software, try installing from the source.

sudo apt install -f
