How can I revert back to the previous dom0 kernel?

Thank you. But how do I configure grubenv then? I only started getting an error message about grubenv after updating Dom0: Grubenv not found with kernel-latest 6.5.8
I normally use the default boot option and my grub.cfg was still default back then.
I just uninstalled kernel-latest but that didn’t change anything.

You need to link /boot/efi/EFI/qubes/grubenv to /boot/grub2/grubenv

I had the same issue, and I don’t think it works if you just create the file in .../EFI/qubes
