I just finished updating a system to F36. It did not go smoothly (/var got filled and dnf system-upgrade failed to remove a bunch of F35 packages). I’ve managed to clean up most of the mess, but the grub menu still shows a F35 kernel. I tried to update the menu manually with kernel-install but no luck. I get the following output and the grub menu remains the same as before.
$ sudo kernel-install add 5.17.6-300.fc36.x86_64 /lib/modules/5.17.6-300.fc36.x86_64/vmlinuz
dkms: running auto installation service for kernel 5.17.6-300.fc36.x86_64
Error! Could not locate dkms.conf file.
File: /var/lib/dkms/mba6x_bl/20150428.f1482dd/source/dkms.conf does not exist.
That’s actually normal and it will drop off on its own after a few Fedora 36 kernels have been installed. A few old kernels are left just in case of emergency if you can’t boot to a new one.
The problem isn’t that the old kernels are still there, I know that’s normal. The problem is that there are no F36 kernels on the menu.
Are you able to run a
dnf distro-sync ?
Yes. When I ran it yesterday
dnf distro-sync did its checks and then said “Nothing to do” or something to that effect. I ran it again just now and it looks like it’s installing a new kernel. I’ll reboot after it’s done and see what happened to the grub menu.
After rebooting I find the oldest F35 kernel has been removed from the grub menu but nothing new has been added, even though
dnf distro-sync installed a new kernel.
Oh, it sounds like my recent experience !
Problem to install a kernel
Can you check if you have new (expected vmlinuz) files in
~> ls /boot
So it looks like there are no F36 kernels and only one F35 kernel in /boot, consistent with what shows up in the grub menu.
Yes. Same experience for me…
You can remove completely kernel 5.17.6-300.fc36.x86_64 with this command
sudo dnf erase kernel*5.17.6-300.fc36.x86_64
check in directory /boot and /boot/loader/entries this kernel entry must be gone.
login and open terminal type this:
sudo dnf update
restart. and then you must see new kernel Fedora 36 in your grub menu bootloader.
Yes, I did that.
I agree it should work as you describe, but it doesn’t !
No fc36 file, no new grub menu line.
That command has the side effect of removing a very large number of other packages, surely there’s a way to reinstall the kernel without triggering a mass removal of packages from the system.
Do you have tried it? This is not removing large packages dependency at least in my fedora 37 linux system. I think this is safe to do that. See my SS below
Interesting, it looks like you have several F37 kernels on your system. I don’t have that.
On my system I was able to remove and reinstall the most recent F36 kernel (5.17.7) without affecting other packages. But if I try to remove kernel 5.17.6-300.fc36 I get this:
sudo dnf remove kernel\*5.17.6\*fc36\* --noautoremove

Remove 71 Packages

Is this ok [y/N]:
can you manually remove them with individually with
sudo rpm -e --nodeps <kernel package>
Not exactly like that, I use Fedora 37 or rawhide, I’ve upgraded yesterday from fedora 36 beta. The upgraded process is like fedora as usual flawlessly and smoothly haha I upgraded because I want to know if my old laptop which doesn’t support uefi still can upgrade to use fedora 37 in the future release, and at least I know it’s working well.
I also have tried your command above. but still no include large dependency when i tried to remove kernel 5.17.7-300.fc36 with your command above. see my SS below:
I expect that would remove it, but it seems kind of risky to use the --nodeps here.
It looks like the reason for the mass removal of packages was that 5.17.6 was the only version for the kernel-headers package. I learned in another thread that the kernel-headers package is not necessarily provided for every kernel; if no changes to userspace headers occurs in a new kernel release then the headers for the earlier kernel version can still be used. So I was able to remove kernel 5.17.6 with
dnf remove kernel-core-5.17.6-300.fc36 and it only removed that kernel version and its modules and not dozens of other packages.
And the reason the grub menu didn’t update was that a bug in systemd kernel-install which causes it to put the kernel files in /boot/efi rather than in /boot. Fix was to delete /boot/efi/<machine id>. Details here:
I tried your solution, but it doesn’t work. I just updated OS to Fedora36, and I also find this bug.
I updated fedora kernel belows:
sudo dnf upgrade
When the system is updated, I reboot the system. And I found the new kernel has not shown in grub menu.
To solve this problem, I did that:
~ sudo sed -i ‘s/GRUB_ENABLE_BLSCFG=true/GRUB_ENABLE_BLSCFG=false/g’ /etc/default/grub
~ sudo grub2-mkconfig -o /boot/grub2/grub.cfg
~ sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
But how to fix this bug? Please help.
