Valve announced that starting with the next version of Ubuntu (19.10), it will no longer support Steam on Ubuntu, the most widespread version of Linux, due to the removal of distribution support for packages. 32 bit. It all started when Canonical, the developer of Ubuntu, announced that it seemed to completely drop support for the 32-bit version in Ubuntu 19.10. However, after a public outcry, the company provided further clarification (or even a change of heart) that support for the next 32-bit version would be limited, however (although updates to the 32-bit libraries bits are no longer provided, effectively leaving them in a frozen state). Following Canonical's initial announcement, a developer at Valve requested Twitter to inform users that Steam would no longer support future versions of Ubuntu.
Steam 19.10 and future versions will not be officially supported by Steam or recommended to our users. We'll be looking at ways to minimize the risk of outages for existing users, but we'll also focus on a different distribution, currently to be determined. Jun 22, 2019 This doesn't mean Valve is turning its back on Linux as a whole, because, as the developer pointed out, the company is trying to focus on supporting a different distribution than Ubuntu. This will be uncomfortable for many users of Ubuntu or another distribution based on the operating system. So what is the problem with the support for 32-bit support? Well, even if the Steam client isn't affected, there are still plenty of older 32-bit games on Steam, and all of this won't work anymore. And there are many titles that many people still want to play.
