Kernel problem

[maromania]

Hi

In CL 8.8 I have a problem, the kernel not loaded.
Almalinux + CL + cPanel

sudo grub2-mkconfig -o /boot/grub2/grub.cfg
Generating grub configuration file ...
/usr/bin/grub2-editenv: error: cannot rename the file /boot/grub2/grubenv.new to /boot/grub2/grubenv: No such fileor directory.

How to fix it please ?

Hi,

Do you have the /boot/grub2 mounted? What is inside when you list it?

ls -la /boot/grub2

Okay, do you have the /boot/efi/ mounted?

Hey there!

Can you confirm the kernel that it's loading? It's loading .15.1 instead of 13.2, I bet, are you able to run rpm -qa|grep kernel as well?

To sum it up, here's what I need you to run:

uname -r

rpm -qa| grep kernel

And in order to attempt to fix it:

grub2-mkconfig -o /etc/grub2.cfg
grub2-mkconfig -o /etc/grub2-efi.cfg
grub2-mkconfig -o /boot/grub2/grub.cfg
grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg​

rsync -avP /boot/efi/EFI/centos/ /boot/efi/EFI/almalinux/
grubby --set-default /boot/vmlinuz-4.18.0-477.13.1.lve.1.el8.x86_64
cp -rp /boot/efi/EFI/almalinux/grubenv /boot/efi/EFI/centos/grubenv​

Do give it a try.

Cheers!
