Description of problem: # dnf system-upgrade download --refresh --releasever=26 fails because of lz4-1.7.5-1.fc25.i686. Removing this package in Fedora 25 would result in removing lot of other packages too (see attached f25_remove_lz4.log ). On the other hand, upgrading with --allowerasing will remove lz4-1.7.5-1.fc25.i686 but not other packages (f25_26_allowerasing.log). Version-Release number of selected component (if applicable): lz4-1.7.5-1.fc25.i686 dnf-1.1.10-6.fc25.noarch dnf-plugin-system-upgrade-0.7.1-4.fc25.noarch How reproducible: Always Steps to Reproduce: 1. Install lz4-1.7.5-1.fc25.i686 2. Try dnf system-upgrade download --refresh --releasever=26 Expected results: Upgrading should work without --allowerasing. Additional info: I don't know Gnome Software upgrade behaviour in these cases, it might not work correctly?

It seems lz4 used to be multilib and now it isn't, and that's why i686 version needs to be erased. I'm not sure if there's something that can be done using obsoletes that would improve this experience.

The bug you've linked as duplicate is about "Old version of lz4 remains installed after upgrade" and that is further duplicate of "Upgrade is not working". This one is about "One should not need to run upgrade with --allowerasing". Difference is clear if you read Expected results section in this report...
