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.

Hello,

Firstly basic situation about my OS:
rpm -qa|grep dnf

When I make sudo dnf update I have following result (example with 3.10.0-957.1.3.el7.x86_64):

I have installed all kernels kernel-3.10.0-957.5.1.el7.x86_64 or 3.10.0-957.1.3.el7.x86_64 or kernel-3.10.0-957.el7.x86_64 and
all work properly...
Frankly speaking, I do not understand the reason, because if I use sudo yum update, all looks O.K.

Comment 2 Bob 2019-02-23 13:43:20 UTC 
I believe I'm having the same problem. It happens since 2019-02-14 on all CentOS 7 systems.

Dnf update always want's to reinstall kernel 3.10.0-957.5.1. But the reinstalled kernel is never loaded after rebooting (no menuentry in grub.cfg is created). Only after reinstalling the kernel with yum the kernel is loaded on reboot. But dnf update will still reinstall the kernel 3.10.0-957.5.1 and the menuentry for 3.10.0-957.5.1 is removed again from grub.cfg.

This is the transaction before the first reinstall happened:

Comment 3 Akemi Yagi 2019-02-25 07:05:29 UTC 
Updating libsolv to 0.6.35 seems to resolve the issue. See bug #1668256 and further upstream #1554820 for details.
