Canonical announced today that it has finally decided completely remove support for 32-bit architecture in the following releases of its popular Ubuntu distribution.
Last year, during the Ubuntu 18.04 LTS Bionic Beaver development cycle, Canonical announced that they would stop offering 32-bit install images, an action that was copied by all versions of Ubuntu 18.10 Cosmic Cuttlefish. But, the 32-bit repositories were still there.
Because Ubuntu 18.04 is a long-term support release, receiving updates for five years, Canonical disabled the ability to upgrade from Ubuntu 18.04 LTS to Ubuntu 18.10 for 32-bit systems, but now, they have announced that Starting with Ubuntu 19.10 Eoan Ermine, 32-bit support will be removed completely.
32-bit applications will still be able to run on Ubuntu
Although Canonical no longer offers support for 32-bit programs for their upcoming releases, the company mentioned that it will still be possible to run 32-bit applications on Ubuntu if users want it to. This can be accomplished if developers use a supported filesystem like Snap, Flatpak, or AppImage.
Canonical also mentioned that more details on the end of support for 32-bit architectures will be given in the coming months when Ubuntu 19.10 is nearing its final release, this is so that 32-bit application users know how to proceed. Ubuntu 19.10 Eoan Ermine has a planned release date of October 17, 2019.
