Upcoming changes in Fedora 31 include: stop creating the main repositories for the i686 architecture. The formation of multi-lib repositories for x86_64 environments will be preserved and i686 packages will be saved in them.
The change has not yet been reviewed by the FESCo (Fedora Engineering Steering Committee), which is responsible for the technical part of the development of the Fedora distribution.
The offer complements in implementation and embodied in the rawhide branch to stop creating a boot image of the Linux kernel for the i686 architecture. The discontinuation of the kernel package ends the ability to install Fedora on 32-bit x86 systems. At the same time, users are not deprived of the opportunity to update already installed systems from repositories. The new proposal calls into question this possibility, as users will be forced to use outdated kernel packages containing unpatched vulnerabilities.
In fact, 32-bit repositories remain necessary only for debugging and testing multilib packages that allow 32-bit programs to run in a 64-bit environment. But this task can now be solved using the package build system .
