Package Management under Linux: apt, yum and dnf Compared
Learn how the package management tools apt, yum and dnf differ. We show you the advantages and disadvantages for various Linux distributions and help you choose.
Introduction
Linux offers a variety of distributions, each with its own package management system. The three most well-known are apt (Debian/Ubuntu), yum (older Red Hat-based systems), and dnf (modern Fedora/RHEL). In this article, we compare these tools and show you which one is best suited for your needs.
apt – The Classic for Debian and Ubuntu
apt (Advanced Package Tool) is the standard tool for Debian-based distributions like Ubuntu. It works with .deb packages and offers a simple syntax.
Advantages of apt
- Simplicity: With
apt installandapt update, you handle most tasks. - Dependency resolution: apt resolves dependencies automatically and reliably.
- Large package selection: The repositories of Debian and Ubuntu are huge.
Disadvantages of apt
- Performance: With large updates, apt can be somewhat slower than newer tools.
- No integrated history: Unlike dnf, apt does not show a detailed transaction history.
yum – The Old Faithful for RHEL/CentOS 7
yum (Yellowdog Updater Modified) was the standard for Red Hat Enterprise Linux (RHEL) and CentOS 7 for a long time. It uses .rpm packages.
Advantages of yum
- Proven: yum has been in use for years and is extremely stable.
- Plugins: Extensible through numerous plugins.
Disadvantages of yum
- Slow: yum is often sluggish, especially with metadata processing.
- Outdated: yum is no longer actively developed and is being replaced by dnf.
dnf – The Modern Successor to yum
dnf (Dandified YUM) is the successor to yum and is used in Fedora, RHEL 8+, and CentOS 8+. It is based on the same RPM technology but is faster and more modular.
Advantages of dnf
- Speed: dnf is significantly faster than yum, especially with metadata processing.
- Better dependency resolution: dnf resolves conflicts more efficiently.
- Transaction history: You can easily undo past actions.
- Python 3: dnf is fully ported to Python 3.
Disadvantages of dnf
- Compatibility: Some old yum plugins do not work with dnf.
- Learning curve: For yum users, the commands are similar but not identical.
Direct Comparison
| Criterion | apt | yum | dnf |
|---|---|---|---|
| Package format | .deb | .rpm | .rpm |
| Distributions | Debian, Ubuntu, Mint | RHEL 7, CentOS 7 | Fedora, RHEL 8+, CentOS 8+ |
| Speed | Medium | Slow | Fast |
| Dependency resolution | Good | Good | Excellent |
| Transaction history | No | No | Yes |
Conclusion
The choice of package management system depends on your Linux distribution. For Debian/Ubuntu, apt is the first choice. If you use RHEL or CentOS 7, stick with yum but plan to upgrade. For modern Red Hat-based systems, dnf is the best option – it's fast, reliable, and future-proof.
