Unable to install with custom partitioning.

How did you upgrade to 22.04? (Fresh install / Upgrade)

Fresh Custom install

Related Application and/or Package Version (run apt policy $PACKAGE NAME):

Installer

Issue/Bug Description:

Attempting to experiment with btrfs root filesystem. Had previously done a clean default install, rebooted to install media, manually wiped the luks header with dd, created a new disk label (gpt) and recreated partitions using same sizes as the default install, manually formated nvme0np3 as a luks container. rebooted and reran the installer selecting Custom partitioning.

Attempted to unlock the luks container in order to create VG & Root LVM got following error.

Decryptyion Error: The decrypted volume does not have a LVM partiton on it.

Steps to reproduce (if you know):

Run installer with custom partitioning
Create a layout comparable to the default install
Manually format nvme0n1p3 as luks container.
reboot
Attempt install with custom partitioning
Attempt to unlock Luks container

Expected behavior:

I should be able to perform an encrypted install with custom partitioning.

Btrfs isn't compoatible with LVM unfortunately. There's a btrfs root default PR at pop-os/distinst#286
