Understanding What a .deb File Is

Before we dive into how to install .deb file in Ubuntu, let’s get clear on what we’re dealing with. A .deb file is a Debian package, the Linux world’s equivalent of a Windows .exe or a Mac .dmg.

Think of it as a lunchbox with all the ingredients for your favorite software sandwich.

Ubuntu, being a Debian cousin, loves .deb files. They let you install apps that aren’t in the Ubuntu Software Center, like early releases from developers or niche tools you can’t find in the default repos. Knowing how to install .deb file in Ubuntu means you can bypass the middleman and get the software you want, when you want it.
