What kind of packages does it use?

The .DEB format uses the original Debian repository, ensuring compatibility with all software developed for Debian-based systems and avoiding issues with missing libraries. It doesn’t clutter your system with dummy partitions or megabytes of unnecessary files, and you can find all the software you need beyond the App Store. You can also use the AppImage format, which runs without altering or installing anything on your disk and includes everything needed for any task. To browse AppImage programs, just search the built-in App Store — you’ll find 1,346 categorized applications, ready to use without touching your file system


How do I find the program I've always used?

The App Store includes all Linux applications, and your system can instantly run any AppImage file online. Most software sites, both free and commercial, offer a .DEB package for Debian-based systems or an updated AppImage file of your favorite app. Simply download and install it with the gDebi installer, which handles all dependencies. For AppImage files, simply grant executable permissions and launch them with a single click .AppImage packages do not modify your libraries or filesystem in any way. You'll have access to almost any application available for Linux; a simple web search for Debian-compatible applications is all it takes.

What if I need assistance?

Based on Debian Stable, you’ll find all the help you need in existing Debian guides and blogs.
