You are right. I revised apt log and grub-efi-amd64-signed was NOT updated, in fact, the version I have installed now is 1+2.06+13, but all other grub packages have 2.06-3~deb11u5. Now, if I run apt update, and apt list --upgradable it shows: grub-common/unstable 2.12~rc1-7 amd64 [upgradable from: 2.06-3~deb11u5] grub-efi-amd64-bin/unstable 2.12~rc1-7 amd64 [upgradable from: 2.06-3~deb11u5] grub-efi-amd64-signed/unstable 1+2.12~rc1+7 amd64 [upgradable from: 1+2.06+13] grub-efi-amd64/unstable 2.12~rc1-7 amd64 [upgradable from: 2.06-3~deb11u5] grub2-common/unstable 2.12~rc1-7 amd64 [upgradable from: 2.06-3~deb11u5] All of them with version 2.12~rc1-7 Is it safe to upgrade now? I'll wait a bit until I hear from the package maintainers.
