Ubuntu’s 32-bit desktop installers will soon be a thing of the past.
A mailing list post this week, spearheaded by a proposal from Canonical’s Dimitri John Ledkov, discussing how best to phase out support for 32-bit Ubuntu ISOs.
Ubuntu is dropping 32-bit desktop installers later this year
And developers are keen to move forward, with an eagerness to drop Ubuntu 32-bit desktop and server installers later this year.
The debate over whether to continue providing 32-bit Ubuntu installs has nothing to do with forced obsolescence and everything to do with security and what people are using.
As Ledkov explains, maintaining and building 32-bit Ubuntu images is “not free” and “comes at the cost of utilizing our build farm, QA and validation time.”
”Whilst we have scalable build-farms, i386 still requires all packages, auto package tests, and ISOs to be revalidated across our infrastructure [and] take up mirror space & bandwidth,” the software engineer adds.
Many software vendors have already stopped supporting 32-bit Linux distros
Beyond the effort and infrastructure costs in producing 32-bit Ubuntu ISOs is the fact that scores of third-party software vendors have already dropped 32-bit Linux support, or plan to do so in the near future.
In January Google axed 32-bit downloads of Chrome for Linux, following similar decisions on OS X and Windows the previous year.
Reduced upstream software support married with reduced upstream security support equals …Squeaky bum time for the aged architecture. This raises questions of how Ubuntu can offer effective security support on such systems.
Draft Plan Suggests Dropping 32-bit Desktop Images
How do you phase out support for a legacy architecture?
Carefully, is the answer.
Ubuntu will be keen to send the message that 32-bit Ubuntu builds are on the way out
The timetable up for discussion provides a piecemeal approach with the goal of offering absolutely zero installable 32-bit support by Ubuntu 18.10.
To get there Ubuntu 16.10 through 17.10 would continue to offer 32-bit Ubuntu support but in a reduced capacity: it will drop installable 32-bit desktop and server images.
Alternative installation images, like the net-boot installer, cloud images, and others would still be provided for these releases.
Ledkov’s timetable suggests that Ubuntu 18.04 LTS “…provide i386 port to run legacy applications on amd64” but lose all alternative, cloud and kernel installers.
With Ubuntu 18.10 support for 32-bit PCs will disappear completely. Users would only be able to run 32-bit software using Snaps, containers, or virtual machines.
If these dates stick that would make April 2021 the official deadline date for all official 32-bit OS support.
More Discussion Needed
Ubuntu developers will be keen to send the message that 32-bit Ubuntu builds are on the way out, and they’re right to do so.
Carefully planning to limit the impact such a decision would have on users, businesses and the free software community at large is crucial.
For example, what happens to users already running 32-bit installs? Will 32-bit users be able to upgrade to a newer release? If not, why not? And how will distributions like Lubuntu and Ubuntu MATE be affected?
Questions, questions, questions!
