I'm still sad that Linux dropped support for i486 and early-i586 CPUs.
And more disappointed that distributions especially Debian the "universal operating system" has dropped support for i586 already (and is dropping support for i686)
Open-source doesn't have the same pressures of commercial software from Apple or Microsoft. I really love the idea of obsessive, perfectionism approach of providing indefinite hardware support to obscure old hardware (but especially once-popular old hardware), with adequate automated testing suites to test ancient hardware.
Maybe with agentic AI coding we'll be able to expand support windows, and even bring back hardware support for older hardware.
> the project lead, Rudra B. Rudra, has had less time to dedicate to the work recently. As a result, the team could not ship a stable 25.10 release this October.
That may not be the biggest deal, because Ubuntu 25.10 itself is not going to be stable, thanks to switching from GNU coreutils to the uutils Rust rewrite, with Ubuntu 25.10 being a "see what breaks and fix it" canary before the long-term support 26.04 release in 6 months.
I think this is premature and a big mistake for Linux.
The costs of distros and the kernel steadily dropping older x86 support over the last few years never causes an outcry but it's an erosion of what made Linux great. Especially for non-English speaking people in less developed countries.
Open-source maintenance is not a obligation, but it's sad there is not more people pushing to maintain support. Especially for the "universal operating system" Debian which was previously a gold standard in architecture support.
I maintain a relatively popular live Linux distro based on Ubuntu and due to user demand will look into a NetBSD variant to continue support (as suggested in this thread), potentially to support legacy 586 and 686 too.
Though a Debian 13 "Trixie" variant with a custom compiled 686 kernel will be much easier than switching to NetBSD, it appears like NetBSD has more commitment to longer-term arch support.
It would be wonderful to develop systems (eg emulation) to make it practical to support architectures as close to indefinitely as possible.
It does feel like a big end of an era moment for Linux and distros here, with the project following the kind of decision making of big tech companies rather than the ideals of computer enthusiasts.
Right now these deprecation decisions will directly make me spend time working at layers of abstraction I wasn't intending to in order to mitigate the upstream deprecations of the kernels and distros. The reason I have used the kernel and distros like Debian has been to offload that work to the specialist maintainers of the open-source community.
Debian's tagline is the "universal operating system". It's a distribution with active ports on a very large number of architectures [1], even incredibly obscure ones.
The goal of universal compatibility that separates the Debian project from commercial software and even other open-source projects.
The legacy x86 architecture is still far more popular than some that platforms that Debian advertises as having official support for and there has been x86 based processors manufactured for niche applications until recently, eg, AMD Geode and others.
I find it really unfortunate Debian Project is removing official support for new x86 installations. The silver lining is it seems like they'll be an unofficial port and it's likely niche distributions like MX Linux and AntiX will maintain their own builds.
It would be ideal if open-source can develop stronger mechanims to keep support for the large numbers of these relatively niche architectures (eg, through increased usage of emulation over real hardware).
