Fedora 44 Proposal: The End of 32-bit (i686) Linux Support – What It Means for Users

 

Fedora

Fedora 44 may fully drop 32-bit (i686) support, ending multi-lib packages for legacy software. Learn why this shift is happening, its impact on Linux users, and alternative solutions for running 32-bit apps.


Fedora’s Major Shift Away from i686 Architecture

Fedora Linux has been gradually phasing out 32-bit (i686) support, and with Fedora 44, the distribution may take the final step—completely dropping i686 packages

A new proposal seeks to eliminate multi-lib support for 32-bit applications on 64-bit systems, marking the end of an era for legacy x86 software.

This move aligns with broader industry trends, as most modern software now runs on x86_64 (64-bit) architecture. However, some applications—particularly Steam games and select legacy software—still rely on 32-bit libraries. 

Fedora’s decision aims to reduce maintenance overhead, speed up builds, and optimize repository efficiency.

Why Fedora is Dropping i686 Support

1. Declining Usage & Increased Maintenance Burden

  • Most modern applications have transitioned to 64-bit (x86_64), making 32-bit support increasingly obsolete.

  • Maintaining i686 packages requires extra build resources, testing, and patching, diverting efforts from core development.

  • Major upstream projects (like GNOME, KDE, and GCC) have already dropped 32-bit support, forcing Fedora to maintain downstream patches.

2. Performance & Infrastructure Benefits

  • Faster x86_64 builds: Removing i686 packages frees up build servers, accelerating 64-bit package compilation.

  • Smaller repositories: Eliminating ~10,000 32-bit packages reduces metadata size, speeding up DNF operations (dependency resolution, updates, and installs).

  • Simplified maintenance: Fewer architecture-specific bugs and compatibility issues.

3. Alternatives for Legacy 32-bit Software

While native i686 packages will no longer be available, users needing 32-bit support can leverage:

  • Flatpak (containerized apps with bundled dependencies)

  • Steam Runtime (Valve’s compatibility layer for 32-bit games)

  • Virtual machines (running older distros for legacy software)

Industry Implications: Is This the End of 32-bit Linux?

Fedora isn’t alone—Ubuntu, Arch Linux, and openSUSE have also reduced 32-bit support. This shift reflects broader trends:

  • Hardware evolution: Modern CPUs (Intel/AMD) prioritize 64-bit performance.

  • Security & efficiency: 64-bit systems offer better memory addressing and exploit mitigations (like NX bit, ASLR).

  • Gaming & proprietary software: Valve’s Proton (Steam Play) and Wine increasingly favor 64-bit compatibility.

However, some niche use cases (retro gaming, embedded systems, and legacy enterprise software) may still require 32-bit support.

Fedora 44 Proposal Status & Next Steps

The change must still be approved by the Fedora Engineering and Steering Committee (FESCo). If passed, Fedora 44 will:

✅ Stop building i686 packages entirely

✅ Remove multi-lib (32-bit on 64-bit) support

✅ Encourage Flatpak/containerized solutions for legacy needs

Conclusion: Should Other Linux Distros Follow Fedora’s Lead?

Fedora’s move signals a necessary evolution—prioritizing modern infrastructure over legacy compatibility. 

While some users may face short-term hurdles, the long-term benefits (faster updates, reduced maintenance, and optimized performance) make this a strategic win.

What do you think? Should all Linux distributions drop 32-bit support, or is there still a case for keeping i686 alive?


FAQs

Q: Will Fedora 44 still run 32-bit apps?

A: Only via Flatpak, Steam Runtime, or VMs—native i686 packages will be gone.

Q: What about Steam games that require 32-bit?

A: Valve’s Steam Runtime provides compatibility layers.

Q: Will other Linux distros follow?

A: Likely—Ubuntu and Arch have already reduced 32-bit support.
