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.

Fixed In Version: yum-3.4.3-154.el7
Doc Type: Release Note
Doc Text:
*yum* no longer reports package conflicts after installing _ipa-client_ After the user installed the _ipa-client_ package, the *yum* utility unexpectedly reported package conflicts between the _ipa_ and _freeipa_ packages. These errors occurred after failed transactions or after using the "yum check" command. With this update, *yum* no longer reports errors about self-conflicting packages because such conflicts are allowed by RPM. As a result, *yum* no longer displays the described errors after installing _ipa-client_.

Description Marian Ganisin 2016-08-25 11:56:59 UTC 
Description of problem:

Historically couple of packages seem to conflict with freeipa counterparts on purpose:

$ rpm -qp --conflicts ipa-client-4.4.0-7.el7.x86_64.rpm 
freeipa-client

However new version included in RHEL-7.3 introduced new rpm provides:

$ rpm -qp --provides ipa-client-4.4.0-7.el7.x86_64.rpm 
freeipa-client = 4.4.0
ipa-client = 4.4.0-7.el7
ipa-client(x86-64) = 4.4.0-7.el7

Due to that a curious state occurred which resulted in ipa-client conflicting with itself (and all other packages that have this provides & conflicts pair implemented)

This seems to break _neither_ installation _nor_ update. From that  point of view everything seems to be fine.

However having package conflicting with itself looks unusual.

Furthermore 'yum check' command exits with non-zero (1) status code and produces following output:

$ yum check
Loaded plugins: product-id, search-disabled-repos, subscription-manager
Error: check all
ipa-client-4.4.0-7.el7.x86_64 has installed conflicts freeipa-client: ipa-client-4.4.0-7.el7.x86_64
ipa-client-common-4.4.0-7.el7.noarch has installed conflicts freeipa-client-common: ipa-client-common-4.4.0-7.el7.noarch
ipa-common-4.4.0-7.el7.noarch has installed conflicts freeipa-common: ipa-common-4.4.0-7.el7.noarch
ipa-python-compat-4.4.0-7.el7.noarch has installed conflicts freeipa-python-compat: ipa-python-compat-4.4.0-7.el7.noarch



Version-Release number of selected component (if applicable):
4.4.0-7

How reproducible:
always

Steps to Reproduce:
1. install ipa-client (and/or others)
2. run yum check


Actual results:
Packages conflicting with itself present
yum check broken! it always reports errors despite to fact everything seems to be fine

Expected results:
Possibly no packages conflicting with itself
functional yum check
Comment 2 Martin Bašti 2016-08-31 13:31:44 UTC 
Hello yum team, can you please check if this is bug on yum side? It works as expected, there is only one issue with `yum check`

Will fixing yum check also fix package-cleanup?

Comment 17 Dax Kelson 2017-02-27 17:53:53 UTC 
Until this gets fixed for real, I'm using this temporary workaround in our training VMs (which only live for a week at a time).

sed -i "/for creq in pkg.conflicts:/a\                if creq[0].startswith('freeipa'): continue" /usr/lib/python2.7/site-packages/yum/rpmsack.py
Comment 20 Paul Stauffer 2017-03-09 09:53:00 UTC 
FWIW, another (3rd party) affected package is nvidia-kmod from Nvidia's cuda repo:

Package 1:nvidia-kmod-367.48-2.el7.x86_64 has installed conflicts nvidia-uvm-kmod: 1:nvidia-kmod-367.48-2.el7.x86_64

$ rpm -q --conflicts nvidia-kmod-367.48-2.el7
nvidia-uvm-kmod
$ rpm -q --provides nvidia-kmod-367.48-2.el7
nvidia-kmod = 1:367.48-2.el7
nvidia-kmod(x86-64) = 1:367.48-2.el7
nvidia-uvm-kmod = 367.48-2.el7

Thought I'd note this here to assist anyone else searching for an explanation of this problem as related to that package.

Thank you!  We have already identified the problem and it turns out it has been fixed upstream in the past:

commit 1ff69afbb78e9303a0d9859d941371eaedbb6842
Author: James Antill <james>
Date:   Mon Sep 22 16:22:42 2014 -0400

    Have "yum check" ignore self conflicts.

We're going to include the patch in the next minor release of RHEL.

Comment 24 Michaël Van de Borne 2017-03-20 21:03:03 UTC 
Although this error might not seem blocking, it completely blocks the upgrade of a large hadoop cluster, since Ambari won't install anything if this check does not pass. May you have any workaround so that the error code returned would be 0?

This issue appears to only occur on recently installed machine 

$ uname -a
Linux saturn 3.10.0-514.26.2.el7.x86_64 #1 SMP Tue Jul 4 15:04:05 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Never noticed before but  my older machine with exact same version but different installation and history showed exact same response on yum check. Appears a repeatable endemic issue?

Hey,

The latest version of yum in centos doesn't include this bug fix.  Actually, the patch has been upstream for some time:

commit 1ff69afbb78e9303a0d9859d941371eaedbb6842
Author: James Antill <james>
Date:   Mon Sep 22 16:22:42 2014 -0400

    Have "yum check" ignore self conflicts.

We're planning on including it in the next RHEL-7 minor release, so it should eventually land in centos as well.

Hope that helps!

Hi 
Thanks - was only advising of bugs continuing existance at the Centos level which should reflect the RedHat state.

Comment 38 Ed Greenberg 2017-09-29 14:41:52 UTC 
So for the benefit of simple sysadmins who are reading this bug, the resolution at the operational level is to do 'yum update yum' and then 'yum update'.
