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 Karel Srot 2019-08-23 11:27:50 UTC

Description of problem:

See bug 1726141 for some background, esp. #c13.

I do see a dnf crashing when having a repo with zck compressed repodata only. When there are both zck and other (sqlite.bz2, gz) repodata the coredump is not happening (this was fixed fixed in 1726141).

e.g. command
# dnf list --available
crashes

dnf-4.2.7-4.el8.noarch
libdnf-0.35.1-5.el8.x86_64
librepo-1.10.3-2.el8.x86_64

On F30 the scenario works fine.

I create a PR that add additional test whether primary is part of downloaded metadata. https://github.com/rpm-software-management/libdnf/pull/802
