Description of problem: "dnf update --allowerasing" should update the packages, not just remove them. This is hardly justifiable dependency resolution. Version-Release number of selected component (if applicable): $ rpm -q dnf dnf-2.3.0_1-11g53e2ef5.fc27.noarch $ rpm -q libsolv libsolv-0.6.26-26g691c2d6.fc27.x86_64 How reproducible: Steps to Reproduce: 1. 2. 3.

This is hardly justifiable result, since I am pretty sure I don't want to remove the packages. I just want to update them. Additional info:
Actually now I noticed that I tried to install EPEL7 packages into my Rawhide, that was the reason for the missing dependencies. But still, update should not result in pure "remove" action.
Sounds like bug in libsolv...
Vit, could you run dnf with --debugsolver and attach debugdata directory?
Created attachment 1275917 [details] debugdata Of course I don't have the original environment in that specific state available anymore, but I tried to recreate with a limited test case.
This bug appears to have been reported against 'rawhide' during the Fedora 27 development cycle. Changing version to '27'.

This message is a reminder that Fedora 27 is nearing its end of life. On 2018-Nov-30 Fedora will stop maintaining and issuing updates for Fedora 27. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '27'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 27 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
The problem is still valid. Please Igor is there any progress on the issue?
I've tried to play with testcase, but all versions of libsolv I've tried report: Results differ: -erase fedora-packager-0.6.0.1-2.fc26.noarch@@System -erase mock-1.3.4-1.fc26.noarch@@System -erase mock-lvm-1.3.4-1.fc26.noarch@@System So either it is bug in dnf/libdnf or it is just producing incorrect testcase.
Igor, I'm curious as to how you can close this bug with worksforme when there is apparently a bug still in existence? George...

There is an easy reproducer: Find package that requires versioned dependency like git-2.19.2-1.fc29 that requires git-core-2.19.2-1.fc29. Then following command will do the job: sudo dnf upgrade git -x git-core-2.19.2-1.fc29 --allowerasing --best
Thanks for reproducer.

Ok, I can reproduce now with testsolv. Looking.
I belive that for proper investigation you need libsolv with https://github.com/openSUSE/libsolv/commit/0302dce36cb5066a5c818d616a047dc93cfd025d.
