Issue
What were you trying to do that didn't work?
Trying to execute yum update --security fails with conflicts when having some multiarch packages:
# yum update --security
[...]
Error:
Problem: zlib-1.2.11-21.el8_7.i686 from @System does not belong to a distupgrade repository
- cannot install both zlib-1.2.11-25.el8.x86_64 from os and zlib-1.2.11-21.el8_7.x86_64 from @System
- cannot install both zlib-1.2.11-25.el8.x86_64 from os and zlib-1.2.11-21.el8_7.x86_64 from os

- cannot install the best update candidate for package zlib-1.2.11-21.el8_7.x86_64
(try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
Please provide the package NVR for which bug is seen:
libdnf-0.63.0-17.el8_9.x86_64

How reproducible:
Always
Steps to reproduce
Update a RHEL8.9 system to latest, without having i686 packages initially
# yum -y update
Install a few i686 non-latest packages including an old glibc
# yum -y install glibc-2.28-225.el8.i686 libldb-2.6.1-1.el8.i686 zlib-1.2.11-21.el8_7.i686 zlib-devel-1.2.11-21.el8_7.x86_64
Try executing security update
# yum update --security
