Just for the records: If one purges grub-common along with upgrading the other packages, one gets the following: /usr/share/doc# l grub* -d drwxr-xr-x 1 root root 184 Nov 4 01:57 grub2-common lrwxrwxrwx 1 root root 18 Oct 2 2023 grub-efi-amd64 -> grub-efi-amd64-bin drwxr-xr-x 1 root root 108 Nov 4 01:57 grub-efi-amd64-bin lrwxrwxrwx 1 root root 11 Jun 19 2021 grub-efi -> grub-common lrwxrwxrwx 1 root root 11 Jul 10 2024 grub-efi-amd64-unsigned -> grub-common lrwxrwxrwx 1 root root 11 May 19 2011 grub-pc-bin -> grub-common
with the last three symlinks dangling. Cheers, Chris.
