I've confirmed this with a new 19.04 install, and it's not just the
d-r-u process.
In a manually configured system with:
sda3 -> LUKS_BOOT > /boot/
sda4 -> sda4_crypt -> LVM -> /dev/mapper/ubuntu-rootfs -> /
# grep -rn GRUB_ENABLE_CRYPTODISK /etc/default/grub /etc/grub.d/
/usr/lib/grub/ /usr/sbin/grub* /usr/share/grub/
/etc/default/grub:33:GRUB_ENABLE_CRYPTODISK=y
Binary file /usr/sbin/grub-install matches
/usr/sbin/grub-mkconfig:245: GRUB_ENABLE_CRYPTODISK \
/usr/share/grub/grub-mkconfig_lib:77: if [ x$GRUB_ENABLE_CRYPTODISK = xy ];
then
/usr/share/grub/grub-mkconfig_lib:162: if [ x$GRUB_ENABLE_CRYPTODISK = xy ];
then
# grub-install /dev/sda
# update-grub
both fail to add the luks and crypto modules. Core image doesn't get
them:
grub-install: info: grub-mkimage --directory '/usr/lib/grub/i386-pc'
--prefix '/grub' --output '/boot/grub/i386-pc/core.img' --format
'i386-pc' --compression 'auto' --config '/boot/grub/i386-pc/load.cfg'
'ext2' 'biosdisk' 'search_fs_uuid'
and nor does /boot/grub/grub.cfg:
...
menuentry 'Ubuntu' --class ubuntu --class gnu-linux --class gnu --class os
$menuentry_id_option 'gnulinux-simple-a0f21372-a236-4e33-9bfa-9921ca89d5b7' {
