Last June, Canonical dropped the bomb: There will be no more 32-bit Ubuntu versions. And not only that: at first, everything suggested that neither Eoarn Ermine, nor Focal Fossa nor would any future version be compatible with any software that was only available for that architecture, but later they changed their mind ... or rather they said that it had been a misunderstanding, that they never meant to say that.
Probably the main objective of those statements was to see how the community responded. And the community responded: companies like Valve (Steam) or Wine complained, so much so that the first said it would not support the new operating system (Ubuntu 19.10 Eoan Ermine). But we are talking about something that has remained in the past and now we know more details about it. Canonical already knows how they will support 32-bits in Ubuntu 20.04.
Focal Fossa will better support 32-bits
Ubuntu 19.10 came with a small group of 32-bit packages. Those available packages were based on popularity. For Ubuntu 20.04 a few small changes will be made. In this article Are detailed some of the packages they will add or remove. For example, libssl1.0, wine-stable-i386, gcc-8-base and some others will be removed, while others such as Freeglut, libv4l, VDPAU drivers, VA-API drivers and many other libraries will be added.
At Focal Fossa about 1700 packages will be activated in 32-bit versions. In the near future they will add even more, so it seems that Ubuntu 20.04 will be more compatible with 32-bits than is the Eoan Ermine that we have available for just over a month.
The future is 64-bit. All companies are going in that direction, but Valve and Wine, among other companies, made us understand that we are not yet ready to leave behind an architecture that has brought us so many good things, such as old PC games.
