I had to run from shell:
sudo apt-get --reinstall install grub-efi-amd64=2.02~beta2-22ubuntu1 grub-efi-amd64-bin=2.02~beta2-22ubuntu1 grub-common=2.02~beta2-22ubuntu1 grub2-common=2.02~beta2-22ubuntu1 grub-efi-amd64-signed
sudo apt-mark hold grub-efi-amd64 grub-efi-amd64-bin grub-common grub2-common
It's just a temporary fix, grub-efi-amd64-signed package must be updated ASAP.
