Descriptions Link to heading

  • grub-common
/etc/grub.d/*
/usr/bin/grub-mkimage
/usr/sbin/grub-probe

This package contains common files shared by the distinct flavours of GRUB. It is shared between GRUB Legacy and GRUB 2, although a number of files specific to GRUB 2 are here as long as they do not break GRUB Legacy.

  • grub2-common -> grub-common (-> means depend)
/usr/sbin/grub-install
/usr/sbin/grub-reboot
/usr/sbin/grub-set-default
/usr/sbin/update-grub

This package contains common files shared by the distinct flavours of GRUB. The files in this package are specific to GRUB 2, and would break GRUB Legacy if installed on the same system.

  • grub-pc-bin -> grub-common
/usr/lib/grub/i386-pc/*.mod

This package contains GRUB modules that have been built for use with the traditional PC/BIOS architecture. It can be installed in parallel with other flavours, but will not automatically install GRUB as the active boot loader nor automatically update grub.cfg on upgrade unless grub-pc is also installed.

  • grub-efi-amd64 -> grub-efi-amd64-bin, grub2-common
/usr/share/bug/grub-efi-amd64/presubj
/usr/share/bug/grub-efi-amd64/script

This is a dependency package for a version of GRUB that has been built for use with the EFI-AMD64 architecture, as used by Intel Macs (unless a BIOS interface has been activated). Installing this package indicates that this version of GRUB should be the active boot loader

  • grub-efi-amd64-bin -> grub-common, grub-efi-amd64-signed
/usr/lib/grub/x86_64-efi/*.mod

This package contains GRUB modules that have been built for use with the EFI-AMD64 architecture, as used by Intel Macs (unless a BIOS interface has been activated). It can be installed in parallel with other flavours, but will not automatically install GRUB as the active boot loader nor automatically update grub.cfg on upgrade unless grub-efi-amd64 is also installed.

  • grub-efi-amd64-signed -> grub-efi-amd64-bin, grub-efi-amd64, grub2-common
/usr/lib/grub
/usr/lib/grub/x86_64-efi-signed
/usr/lib/grub/x86_64-efi-signed/gcdx64.efi.signed
/usr/lib/grub/x86_64-efi-signed/grubnetx64.efi.signed
/usr/lib/grub/x86_64-efi-signed/grubx64.efi.signed
/usr/lib/grub/x86_64-efi-signed/version

This package contains a version of GRUB built for use with the EFI-AMD64 architecture, signed with Canonical’s UEFI signing key.
