You cannot install a full 32-bit kernel or boot a 32-bit-only system this way.

: Linux Mint 19.3 was the final release to offer a 32-bit version, though it is now past its end-of-life (EOL) date. How to Check Your Current Architecture

Facing this backlash, Canonical reversed its decision within days. They agreed to keep a of 32-bit libraries (multiarch) alive to ensure Steam and Wine continued to work on newer 64-bit systems. Where It Stands Today

: Open Settings > About . Look for "OS Type" or "Architecture". Terminal Method : Type uname -m . x86_64 means you are on a 64-bit system. i686 or i386 means you are on a 32-bit system.

For 64-bit-capable hardware, installing modern Ubuntu (24.04 LTS) is strongly recommended.

By 2017, the tech landscape had shifted. Most new processors were 64-bit, and the "technical debt" of maintaining a separate 32-bit version—fixing bugs and ensuring performance—became a massive burden for the Ubuntu community .

The story of "Ubuntu 32-bit" (the architecture) is a classic tale of technological progress, community pushback, and the inevitable passage of time. The Golden Era

sudo dpkg --add-architecture i386 sudo apt update sudo apt install libc6:i386 libstdc++6:i386

Manufacturing plants and industrial facilities often run CNC machines, medical imaging devices, and legacy servers that rely on 32-bit processors. These machines cost hundreds of thousands of dollars and cannot be replaced easily. Ubuntu Server (32-bit) remains a go-to solution for virtualizing or maintaining these controllers.

Note: Ubuntu 20.04 and later do provide official 32-bit installers.

In June 2019, Canonical (the company behind Ubuntu) announced they would drop 32-bit support entirely starting with version 19.10. This sparked an immediate uproar from two massive communities:

: Developing, testing, and patching two separate versions of every software package doubled the workload for developers and automated build systems. Running 32-bit Applications on 64-bit Ubuntu

Some official Ubuntu flavors, such as and Xubuntu , continued to provide 32-bit ISOs much longer than the main distribution, specifically targeting the retro-computing crowd. However, even these are becoming scarcer with each LTS cycle.
