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.

+++ This bug was initially created as a clone of Bug #2172288 +++

Description of problem:
When the .i686 arch of a multilib package is installed first, you can not undo the later transaction which installed the .x86_64 variant.


Version-Release number of selected component (if applicable):
[root@r9 ~]# rpm -q dnf libsolv
dnf-4.14.0-4.el9.noarch
libsolv-0.7.22-1.el9.x86_64

How reproducible:
Everytime

Steps to Reproduce:
1. Do not have libpq installed
2. # yum -y install libpq.i686
3. # yum -y install libpq
4. # yum history undo last      ##This should undo the libpq.x86_64 transaction

Actual results:
Error:
 Problem: problem with installed package libpq-13.5-1.el9.i686
  - libpq-13.5-1.el9.i686 has inferior architecture
  - conflicting requests
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

Expected results:
Since we could install libpq.i686 without .x86_64 in the first place, theres no reason we can't undo the transaction with .x86_64 in it.

Additional info:

Note: I needed to change step 3 to:
3. # yum -y install libpq.x86_64
to reproduce on Fedora 37.

I've created an issue on libsolv (https://github.com/openSUSE/libsolv/issues/525). The issue contains reproducer using libsolv testcase.

The issue is fixed by https://github.com/openSUSE/libsolv/commit/634371f143e5c0d4244dd46084d0aa7ccdb3967c

But it created a side effect. See https://github.com/openSUSE/libsolv/issues/528. The side effect is fixed by https://github.com/openSUSE/libsolv/commit/634371f143e5c0d4244dd46084d0aa7ccdb3967c
