RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:
Stumbled on this because of https://bugzilla.redhat.com/show_bug.cgi?id=1727105. 

Installing inkscape on RHEL8.1 results in yum downgrading a lot of packages in order to fulfil dependencies, since inkscape depends on an older version of poppler:

Transaction Summary
=========================================================================================================================================================================
Install    10 Packages
Downgrade  24 Packages


How can I disable this behaviour? I don't want yum to fail if dependencies are not fulfilled, not downgrade packages and thereby leaving my system in an undesired state (i.e. not up-to-date). 


Version-Release number of selected component (if applicable):
yum-4.2.7-7.el8_1.noarch

How reproducible:
Always

Steps to Reproduce:
1. 'yum install' on package with deps to an old version of a package (inkscape for example, currently)
2.
3.

Actual results:
yum downgrades packages to fulfil the dependencies

Expected results:
yum should fail because dependencies are not met

Additional info:
Comment 1 adam winberg 2019-11-28 11:51:45 UTC 
Typo correction - i _do_ want yum to fail if dependencies are not fulfilled
Comment 2 adam winberg 2019-12-06 08:11:06 UTC 
Anyone? On an enterprise distro you hardly want to downgrade packages and risk end up in a vulnerable state, just to satisfy dependencies. 

Is there really no way to make yum/dnf fail instead?
Comment 3 Jaroslav Mracek 2019-12-11 14:14:42 UTC 
Thank you very much for the report. Please could you provide an additional information about your system? It is needed to properly decide what we can do for you.

Please could you provide outputs form following commands?

yum repolist

yum repoquery --info --installed --available libreoffice-ure inkscape

yum module list


Thanks a lot.
Comment 4 adam winberg 2019-12-11 14:23:35 UTC 
We're using local yum mirrors so the repolist is not so useful to you I think. In the example with inkscape there is only one repo involved (tfolinux-rhel-appstream), which is a copy of the AppStream repo from Red Hat. The repo is copied nightly from Red Hats CDN using Pulp.

Thanks a lot for cooperation. It looks like that the problem is in the latest inkscape build (the issue will be resolved by different bugzilla). The downgrade must be not required to install inkscape.

In reported issue YUM allows to install inkscape even if downgrade of other packages is required. But next upgrade operation will fail because DNF cannot upgrade into the latest packages.

With install operation YUM newer knows if downgrade is intended or not. Or be more general to install/downgrade not the latest dependencies. The upgrade operation is quite clear what is intended and YUM in RHEL will fail if upgrade cannot be performed completely.

I can only propose to use the upgrade/check-update command as an indicator for your system if there are any upgrades available and probably not applicable.

Could you accept the upgrade command as a sufficient workaround to resolve the issue?

I'm not sure I understand - in this case, if a user wants to install inkscape, how would 'yum upgrade' help us from preventing that the install operation downgrades packages?

I am sorry for my confusing comment 5.

The issue with inkscape is that the rebuild of inkscape with latest dependencies provided older packages (broken upgrade path).

The issue will be fixed by rebuild of inkskape then you will not experience (https://bugzilla.redhat.com/show_bug.cgi?id=1783238).

At the present time there is no way how to change the behaviour of the install command to use only the latest packages for dependencies.

But the upgrade command fails when a single package cannot be upgraded into the latest version (requires best=True in /etc/dnf/dnf.conf or --best in commandline).

Since yum/dnf is clearly aware that it is in fact downgrading packages in order to be able to install the desired package it feels like it should be possible to switch that behaviour off.

In cases such as the one with inkscape using '--best' will not make any difference I believe? And according to documentation the '--best' parameter is only relevant to upgrades?

I will create patches that will add a configuration option (`solverflags`) that will allow modification of behaviour by removing of default values. It also requires changes in behaviour of libdnf API therefore I have to consider the bug as a RFE.

I create a patch for dnf/libdnf (https://github.com/rpm-software-management/libdnf/pull/880), but discussion revealed that adding possibility to disable downgrades will brake modular content in RHEL8. After considering all information I have to close the bug as cannot fix. Your issue will be resolved by a new release of inkscape (See: https://bugzilla.redhat.com/show_bug.cgi?id=1783238)
