Problem to install a F36 kernel

I recently updated from F35 to F36 and I have a problem during installation of a kernel:

$ sudo dnf install kernel

Complete!

Result is : there is no /boot/vmlinuz-5.17.7-300.fc36.x86_64 installed
Very strange.
A rpm -ih -vv command says:

I performed latest dnf updates…

In fact, I did have the problem during dnf system upgrade because the new F36 kernel was not activated.
I am running the dnf install kernel from existing

/boot/vmlinuz-5.17.6-200.fc35.x86_64

kernel.

i am stuck !
Thanks for your help.

Same here. I downloaded the rpm and tried to extract the files with cpio to my home directory. The /boot directory is not extracted. However, other computers install this kernel with no issues.

EDIT: But even if the kernel is installed in these other computers, rpm2cpio does not extract the files.

Ahhhh.
I see you are running 35 from this
Kernel: 5.17.6-200.fc35.x86_64 arch
but are trying to install a kernel from 36

I wonder if you had an incomplete upgrade?

I would not use dnf install kernel but instead would use dnf upgrade kernel* so it handled all the parts of the kernel while updating the kernel to the latest.

No, it doesn’t work either

This dnf upgrade kernel* command is not pulling kernel and kernel modules ?

I still don’t understand. :question:

What do df -ai /boot and df -ah /boot report?

I did not feel the upgrade from f35 to f36 was incomplete. How do I check that ? (I might have cleaned up many things already).

That tells me it is possible that the upgrade did not complete successfully. The fact that you booted to an F35 kernel is ?.
It is also possible that the mirrors are not fully in sync with the latest kernel upgrade. If the mirrors are out of sync then wait a while for them to update and try again.

What is the output of ls -l /boot?
You should see at least one F36 kernel as initramfs*fc36* and a matching vmlinuz*fc36*.

If not and you only have the ability to boot to the f35 kernel from grub that is its own issue. To verify things are coherent try dnf distro-sync and see if that does anything to make sure things are properly matching before you do anything more.

Everything is clean, no fc36 files in /boot

You can remove completely kernel kernel-5.17.7-300.fc36.x86_64 with this command
sudo dnf erase kernel*5.17.7-300.fc36.x86_64

check in directory /boot and /boot/loader/entries this kernel entry must be gone.
restart
login and open terminal type this:
sudo dnf update

restart. and then you must see new kernel Fedora 36 in your grub menu bootloader.

I dnf remove kernel*5.17.7* and update again. No success.
I downloaded the kernel-core-5.17.7-300.fc36.x86_64.rpm and rpm -ivh kernel-core-5.17.7-300.fc36.x86_64.rpm with the same “failure” : no expected files in /boot :frowning:

Attempting to install a kernel by downloading one specific rpm is fruitless and a waste of time. This is especially true when using rpm since that does not search for and install the dependencies needed. Dnf makes sure all the dependencies are available and installed.

It appears that definitely the upgrade did not complete successfully since it did not install the fc36 kernel.

Please try dnf list installed kernel and post that output here.
Also post the output of dnf remove kernel*5.17*fc36* and cat /etc/fedora-release

BTW, how did you do the upgrade from 35 to 36? Was it by using the gnome software app or by using dnf system-upgrade?

So weird

I used dnf system-upgrade to jump from f35 to f36.

$ cat /etc/fedora-release
Fedora release 36 (Thirty Six)

I am now in the 35.5 state !?
Do you suggest I remove the fc36 kernel and perform the dnf system-upgrade again ?
Why would this succeed this time ?
Regards

If you have old kernels taking up space on the drive, then you can delete them with the following script (from DNF System Upgrade):

#!/usr/bin/env bash

old_kernels=($(dnf repoquery --installonly --latest-limit=-1 -q))
if [ "${#old_kernels[@]}" -eq 0 ]; then
    echo "No old kernels found"
    exit 0
fi

if ! dnf remove "${old_kernels[@]}"; then
    echo "Failed to remove old kernels"
    exit 1
fi

echo "Removed old kernels"
exit 0

The DNF System Upgrade also has other tips for cleaning the old F35 installation after an upgrade.

Also note that the script dnf used to remove old kernels had a bug and it used to leave artifacts in /lib/modules. You can remove the old artifacts manually from /lib/modules once the kernels have been removed using dnf. Also see Issue 2016630, Removing old kernel-core leaves modules.builtin.alias.bin under /lib/modules.


For completeness, here is my /boot after a DNF System Upgrade to F36. I had 4 of them complete without trouble (and I always follow the official docs). After the reboot into the new kernel I remove all of the old kernels.

I did follow the docs, the problem is not old kernels. The problem is :

How to get out of this weird situation : fedora 36, but not able to get kernels fc36 and corresponding grub menu line ?

Out of curiosity have you tried to reinstall grub?
sudo dnf reinstall grub2-common grub2-efi

The kernel package is a meta package that pulls in all the dependencies and other parts of the kernel.
since you do not have the ‘kernel’ package installed the system does not know what to do, and that is probably the cause of failure to create the initramfs and vmlinuz entries in /boot.

I think the fix is to follow these steps.

  1. dnf remove kernel*fc36* --noautoremove which will remove all the kernel packages from the fc36 install and will not try to remove all the extra packages. On my system there are about 20 or so packages that would be removed which is not really an issue. If you note which dependencies are removed they are easy to reinstall.
  2. dnf install kernel-5.17.7-300-fc36 which should install all the needed kernel packages for fc36.
  3. When #2 completes then ls -l /boot should now show the initramfs and vmlinuz entries for the 5.17.7 kernel

For me, doing dnf remove kernel*fc36* --noautoremove produces a huge list of packages that would be removed (104 altogether, totalling 2.1G in size). I tried instead dnf remove kernel*5.17.7-300.fc36.x86_64 followed by dnf install kernel-5.17.7-300.fc36.x86_64 but that did not put the newly-installed kernel in /boot.

I do see files related to the F36 kernels in /boot/efi. Not sure if they’re supposed to be there or not.
