The FESCo (Fedora Engineering Steering Committee), which is responsible for the technical part of the development of the Fedora distribution, termination of the formation of the main repositories for the i686 architecture. Let us recall that initially consideration of this was postponed to study the possible negative impact of the discontinuation of i686 packages on local module builds.
The solution complements the solution already implemented in the rawhide branch to stop the formation of a boot image of the Linux kernel for the i686 architecture. The discontinuation of the kernel package makes it dangerous to provide the ability to update already installed systems from repositories, as users will be forced to use outdated kernel packages containing unpatched vulnerabilities.
The formation of multi-lib repositories for x86_64 environments will be preserved and i686 packages will be saved in them.
