    How do I set up LUKS full disk encryption on Kubuntu?

    So I'm trying to install Kubuntu will full encryption and manual partitioning.

    I try:
    1024MB FAT32 partition with /boot/efi flagged as "boot"
    1024MB Ext4 partition with /boot
    142GB Ext4 LUKS partition with root

    It gives me a warning "Boot partition not encrypted", tells me it's insecure and I should encrypt it.

    So I delete that partition and just have the following (since I don't need the boot partition separate if it's not unencrypted):
    1024MB FAT32 partition with /boot/efi flagged as "boot"
    143GB Ext4 LUKS partition with root​

    After I install and reboot, GRUB doesn't detect anything and the various remediation steps I tried don't seem to work on Kubuntu.

    Anyone know how I go about setting this up?
