Помогите настроить luks на lvm для двойной загрузки Arch-Ubuntu

В настоящее время я запускаю установку Arch, настроенную с помощью Luks на LVM. Я хотел бы выполнить двойную загрузку с общим / домашним разделом, с двумя отдельными пользователями. Я дошел до загрузки установщика Ubuntu live и разблокировки шифрования luks, но установщик не распознает операционную систему Arch. В настоящее время я использую systemd-boot на Arch. Я не уверен, как настроить разделы lvm таким образом, поэтому любая помощь или направление будут хороши.

Вот мой fdisk -l:
