This release 15.8+ubuntu+1.57-1 is not working on my aptop. Get below error on boot up and PC shuts down:
Verifying shim SBAT: Security Violation Failure Something went terribly wrong [...]
Restoring to earlier version 15.7+ubuntu+1.56-1 and tried re-install and checked the sbat revocation:
sudo mokutil --list-sbat-revocations
sbat,1,2023012900
shim,2
grub,3
grub.debian,4
My current sbat file is as follows:
sbat,1,SBAT Version,sbat,1,https://github.com/rhboot/shim/blob/main/SBAT.md
grub,3,Free Software Foundation,grub,2:2.12-2,https//www.gnu.org/software/grub/
grub.arch,1,Arch Linux,grub,2:2.12-2,https://archlinux.org/packages/core/x86_64/grub/
Please advice.
