[Bug 1565950] Re: Grub 2 fails to boot a kernel on a luks encrypted volume with Secure Boot enabled

[Mathieu Trudel-Lapierre]

There currently are no plans to that effect.

For now; shipping in the devel series, and the installer does not set up
any partitioning automatically that would make use of this. It's "only"
a convenience for people who do their own partitioning, which requires
some prior knowledge to set this up correctly.

I'm not against having this landed as stable updates for bionic and
cosmic; but it would greatly help if people signed up to do the SRU
verification, as this is often what is the bottleneck for releasing
updates.

Title:
  Grub 2 fails to boot a kernel on a luks encrypted volume with Secure
  Boot enabled

Status in grub2 package in Ubuntu:
  Fix Released

Bug description:
  Booting in UEFI  Secure Boot requires that all code loaded up to and
  including the OS kernel be signed.  This includes all grub modules.
  This is accomplished by including selected modules in a single signed
  binary.  However, the modules required for grub to use an encrypted
  volume have been omitted from the binary package and therefore Ubuntu
  cannot boot from an encrypted volume with Secure Boot enabled.  This
  can be corrected as follows.

  
  The debian/build-efi-images file needs to have lines 136-140 changed from:

  GRUB_MODULES="$CD_MODULES
  	lvm
  	mdraid09
  	mdraid1x
  	"

  to:

  GRUB_MODULES="$CD_MODULES
  	cryptodisk
  	gcry_arcfour
  	gcry_blowfish
  	gcry_camellia
  	gcry_cast5
  	gcry_crc
  	gcry_des
  	gcry_dsa
  	gcry_idea
  	gcry_md4
  	gcry_md5
  	gcry_rfc2268
  	gcry_rijndael
