Description jcastran 2023-01-23 15:36:48 UTC

Description of problem:
When a kernel-core dependency is targeted as the install, such as "yum install kernel-core-uname-r", dnf ignores the 3 kernel limit set by installonly_limit

Version-Release number of selected component (if applicable):
dnf-4.7.0-11.el8.noarch
libdnf-0.63.0-11.1.el8.x86_64

How reproducible:
Everytime

Steps to Reproduce:
1. Have 3 (less than latest version) kernel/kernel-cores installed
2. # yum install kernel-core-uname-r
3.

Actual results:
[root@r8 ~]# rpm -q kernel
kernel-4.18.0-372.26.1.el8_6.x86_64
kernel-4.18.0-372.32.1.el8_6.x86_64
kernel-4.18.0-425.3.1.el8.x86_64
 
[root@r8 ~]# rpm -q kernel-core
kernel-core-4.18.0-372.26.1.el8_6.x86_64
kernel-core-4.18.0-372.32.1.el8_6.x86_64
kernel-core-4.18.0-425.3.1.el8.x86_64
 
[root@r8 ~]# yum install kernel-core-uname-r

Installing:
 kernel-core  x86_64  4.18.0-425.10.1.el8_7  rhel-8-for-x86_64-baseos-rpms
Reinstalling:
 kernel-core  x86_64  4.18.0-372.26.1.el8_6  rhel-8-for-x86_64-baseos-rpms
 
[root@r8 ~]# rpm -q kernel
kernel-4.18.0-372.26.1.el8_6.x86_64
kernel-4.18.0-372.32.1.el8_6.x86_64
kernel-4.18.0-425.3.1.el8.x86_64
 
[root@r8 ~]# rpm -q kernel-core
kernel-core-4.18.0-372.32.1.el8_6.x86_64
kernel-core-4.18.0-425.3.1.el8.x86_64
kernel-core-4.18.0-425.10.1.el8_7.x86_64
kernel-core-4.18.0-372.26.1.el8_6.x86_64
 


Expected results:
only 3 kernel/kernel-cores should be installed at a time. The oldest one should be removed when a new kernel is installed. 

Additional info:
This may potentially be the cause for https://bugzilla.redhat.com/show_bug.cgi?id=2163461

Thank you for the report, this is indeed a problem in dnf.

I would like to note though that we discourage installing just kernel-core this way. It will resulting in missing kernel-modules which might lead to a missing functionality on systems.

Issue migration from Bugzilla to Jira is in process at this time. This will be the last message in Jira copied from the Bugzilla bug.

Comment 7 Martin Curlej 2023-08-16 07:56:51 UTC

This bug was migrated to our public Jira instance. From september this year we will stop using bugzilla for bug reporting againts RHEL related products.
