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:
Customer installed a 3rd party DNF plugin named 'langpacks', provided by the dnf-langpacks package from the EPEL repository. This plugin comes with a bug and it breaks DNF:
# dnf -v
Loaded plugins: builddep, changelog, config-manager, copr, debug, debuginfo-install, download, generate_completion_cache, langpacks, needs-restarting, playground, repoclosure, repodiff, repograph, repomanage, reposync

A check to see whether a 3rd party DNF plugin is in use could prevent such an error.

Expected results:
An inhibitor to prevent this kind of issues related to a 3rd party plugin
Thank you Chris for the report. I am thinking with the idea to disable all dnf plugins by default and enable just those we require. Just not sure whether some disabled plugins could be crucial for the dnf regarding customer's setup. WDYT about that, instead of inhibitor? Probably we should discuss it with DNF team as well.

It sounds relevant, and better than creating an inhibitor.
I can't give an exhaustive list, though.
