Public bug reported: Hello!
In my attempt to workaround Bug 1839317 I tried to install shim-signed and enable Secure Boot. Unfortunately, shim-signed binary does not boot for some reason (screen stay black). I want to notice that if I try to boot just with grub-efi-arm64-signed without shim binaries on esp (partition was cleaned up, then grub reinstalled) I getting firmware errors regarding invalid signature. So I guess when firmware validate shim-signed signature it is valid, but then when firmware trying to start shim-signed it get started but for some reason silently fail. ** Affects: shim (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1849863 Title: shim-signed does not boot on Lenovo Yoga C630 WOS with enabled Secure Boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim/+bug/1849863/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
