Ubuntu vs Debian: how they differ
Ubuntu and Debian are often considered side by side. This page compares what each one is built on, how it looks, how software is installed, how updates arrive and what hardware it needs.
Key differences
- Foundation: Ubuntu is built on Debian, while Debian is built independently rather than on another distribution.
- Desktop: both use GNOME.
- Software tools: Ubuntu uses apt and Snap; Debian uses apt, so the commands you learn for one do not carry over.
- Releases: Ubuntu uses long-term releases that stay supported for years; Debian uses numbered releases on a fixed schedule.
- Memory: about 4 GB for Ubuntu against about 2 GB for Debian is a comfortable minimum for a desktop session.
