CloudLinux stuck: Reboot to upgrade kernel

[wpfarm]

I'm having trouble with CloudLinux, saying I need to reboot my system to update the kernel.

After rebooting, the prompt continually remains.

Steps I've taken to resolve:

1. Checked my other server with CL thats working fine. I ran uname -r on the working server and it says:
4.18.0-477.15.1.lve.2.el8.x86_64

2. Check this server and I run uname -r and it says:
4.18.0-477.21.1.el8_8.x86_64

3. OK, so I need to downgrade the kernel.

4. I enter: grubby --set-default "/boot/vmlinuz-4.18.0-477.15.1.lve.2.el8.x86_64" and I get an error:

grep: /boot/grub2/grubenv: No such file or directory
grub2-editenv: error: cannot rename the file /boot/grub2/grubenv.new to /boot/grub2/grubenv: No such file or directory.
The default is /boot/loader/entries/9deea67894474409aac46b279c5f4ed9-4.18.0-477.15.1.lve.2.el8.x86_64.conf with index 1 and kernel /boot/vmlinuz-4.18.0-477.15.1.lve.2.el8.x86_64

5. OK, I look in this forum and find this topic: https://forum.cloudlinux.com/forum/c...kernel-problem and I try..

rpm -qa| grep kernel

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/

cp -rp /boot/efi/EFI/almalinux/grubenv /boot/efi/EFI/centos/grubenv

and I get this error:

6. OK, so I will open a support ticket with CL. But when I create an account, the password email never arrives.

7. So now I'm here, at my wits end. I wish you guys would streamline this installation better. It's been frustrating. I purchased the CL license through cPanel and even they have no idea.

Server Specs:

OVH provider, bare metal, AlmaLinux8 + cPanel, upgraded to CloudLinux using:

wget https://repo.cloudlinux.com/cloudlin...s/cln/cldeploy
sh cldeploy -i
reboot
