Description

Whonix-Host Operating System (OS) ISO

All right, I am making some progress with EFI installation (all tests done in KVM for now, not real hardware). Previously, Calamares would fail at the very beginning, unable to create an EFI partition. Turns out it needed dosfstools to do so, which is installed now on the ISO. So fixed. Then it failed to install grub-efi-amd64 at module bootloader. This is because it needs module sources-media in order to have a working apt sources list to download the package. So it seems we will need this mo…

• [1] Whonix ISO calamares installer shouldn’t require networking for simplicity / usability. (No need to enter WiFi password / circumvention.)
• [2] Whonix ISO Live however should be able to go online.

EFI based systems currently require grub-efi-amd64 which would normally be installed using apt. This violates [1].

Installing grub-efi-amd64 and grub-pc at the same time is not possible since these have Conflicts: (in /debian/control) with each other.

But both grub-efi-amd64 and grub-pc are meta packages. These don’t contain the actual grub binaries.

TODO: look at debian/control · master · Debian GRUB Maintainers / grub · GitLab and install the actual grub binary package instead of the meta package(s). Thereby it might be possible to install both by default

Alternatively grub-efi-amd64 could be cached. (Similar to sudo apt install grub-efi-amd64 --download-only during Whonix-Host ISO build process inside chroot.)
