Wine project developers about problems with the delivery of Wine for Ubuntu 19.10, in the event This release supports 32-bit x86 systems.
Ubuntu developers decide to stop supporting 32-bit x86 architecture to ship the 64-bit version of Wine or to use the 32-bit version in a container based on Ubuntu 18.04. The problem is that the 64-bit version of Wine (Wine64) is not officially supported and contains a large number .
Current builds of Wine for 64-bit distributions are based on Wine32 and require 32-bit libraries.
Typically, in 64-bit environments, the necessary 32-bit libraries are supplied in multiarch packages, but Ubuntu has decided to stop creating such libraries completely. Wine developers immediately the idea of ββa snap package and running in a container, since this is only a temporary solution. It is noted that the 64-bit version of Wine will have to be brought into proper form, but this will take time.
In addition, many current Windows applications continue to ship only in 32-bit builds, and 64-bit applications often come with 32-bit installers (to handle installation attempts in Win32), so the 32-bit version of Wine continues to be developed as the main one. For a long time, Wine64 was positioned only as a tool for launching Win64 applications, not intended for running 32-bit programs, and this feature is reflected in many articles and documentation (now Wine64 is already run Win32 applications, but requires 32-bit libraries).
With similar problems and Valve, many of whose catalog games continue to be 32-bit. Valve intends to support the 32-bit runtime for the Steam Linux client on its own. The Wine developers are not ruling out the possibility of using this runtime to ship 32-bit Wine in Ubuntu 19.10 before the 64-bit version of Wine is ready, so as not to reinvent the wheel and join forces with Valve in the field of supporting 32-bit libraries for Ubuntu.
