Debian vs Ubuntu vs openSUSE: What are the differences?
Key Differences between Debian and Ubuntu and openSUSE
Introduction
Debian, Ubuntu, and openSUSE are popular Linux distributions that offer different features and characteristics. Understanding the key differences between these distributions can help users choose the one that best suits their needs.
-
Package Management: Debian and Ubuntu use the Advanced Packaging Tool (APT) for package management, while openSUSE uses Zypper. APT is known for its vast package repository and smooth upgrades, while Zypper offers a robust dependency resolver and rolling release updates.
-
Release Model: Debian follows a stable release model, where new versions are infrequent but highly stable and reliable. Ubuntu, derived from Debian, offers a more frequent release cycle with long-term support (LTS) releases providing stability. openSUSE, on the other hand, follows a rolling release model, providing the latest software updates continuously.
-
Default Desktop Environment: Ubuntu uses the GNOME desktop environment as the default, while Debian offers different options such as GNOME, Xfce, KDE, and others. openSUSE provides the KDE Plasma desktop as the default but also supports other desktop environments like GNOME and Xfce.
-
Community and Support: Debian has a strong community-driven development model with a focus on stability and security. Ubuntu benefits from the support of its parent company, Canonical, providing commercial support and regular updates. openSUSE combines both community contributions and corporate backing from SUSE, offering extensive documentation and support.
-
Installation Process and Configuration Tools: Debian and Ubuntu use the Debian Installer, known for its flexibility and customization options. Ubuntu adds a user-friendly graphical installer alongside the text-based installer. openSUSE uses the YaST tool, which provides a comprehensive set of configuration features during the installation process.
-
System Administration: Debian and Ubuntu primarily use the sudo command for administrative tasks, while openSUSE uses the su command. This difference influences the default behavior for command execution and privilege escalation. Additionally, Ubuntu employs the Uncomplicated Firewall (UFW) by default, simplifying firewall management for users.
In summary, Debian and Ubuntu offer a stable and widely supported Linux experience, while openSUSE provides a rolling release model with extensive configuration capabilities. The choice between these distributions ultimately depends on the user's needs and preferences.
