Description Vít Ondruch 2023-07-07 21:06:43 UTC
I have following kernel installed:

~~~
$ rpm -qa kernel*
kernel-modules-core-6.5.0-0.rc0.20230705gitd528014517f2.10.fc39.x86_64
kernel-core-6.5.0-0.rc0.20230705gitd528014517f2.10.fc39.x86_64
kernel-modules-6.5.0-0.rc0.20230705gitd528014517f2.10.fc39.x86_64
kernel-6.5.0-0.rc0.20230705gitd528014517f2.10.fc39.x86_64
~~~

and I suspect it has some issues with networking, therefore I'd like to install older version, but it does not look to be possible. The most obvious way does not work:

~~~
$ sudo dnf downgrade --enablerepo=updates{,-testing} kernel\* --releasever 38

Reproducible: Always

Actual Results:  
It seems it is not possible to install older kernel

Expected Results:  
Older kernel can be installed

Comment 1 Vít Ondruch 2023-07-08 19:44:29 UTC
I was able to workaround this by uninstalling all installed kernels:

~~~
$ sudo dnf remove kernel\* --setopt=protect_running_kernel=false
~~~

But this is less then desirable workaround.

Comment 2 Vít Ondruch 2023-07-14 09:03:57 UTC
This is the DNF version in question:

~~~
$ rpm -q dnf5
dnf5-5.0.15-3.fc39.x86_64
~~~

Comment 4 Fedora Release Engineering 2023-08-16 08:12:03 UTC
This bug appears to have been reported against 'rawhide' during the Fedora Linux 39 development cycle.
