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:

Steps to Reproduce:
1. enable source repo
2. install perl-parent
3. yum check-update

Expected results:
yum check-update should not report source packages as updates to anything.

Additional info:
The reported package is from another module:stream. It seems that check-update is just going off version, and not respecting modular filtering. It should just ignore source packages all together since they are not updates to anything.

So, this looks to be due to:

  dnf/cli/cli.py
    check_updates()
    -> returnPkgLists()

  dnf/base.py
       -> _do_package_lists()
          -> _list_pattern()

Where, _list_pattern() will return src RPMs. The solution looks to be something like passing in something like a new "include_src=True" default argument into _do_package_lists that can be overridden in the returnPkgLists() callpath.

Filed PR upstream to illustrate what I mean by the above, feel free to make alterations/changes.

I've created a test for the issue: https://github.com/rpm-software-management/ci-dnf-stack/pull/1198
