I never succeeded installing Ubuntu by choosing something else option. Because I want to change some stuff than the default ones. e.g. partition size, file system to btrfs, not making swap partition, making home partition. I just want to make two partitions: one ESP, and one encrypted luks container and NOT making a separated /boot partition. Every time I try to install in this scheme, I fail. Can anyone please guide me what should I do? Sometimes installation will fail because of error in installing of grub, and sometimes if installation successful, I don't know what to do before restart; edit crypttab, what and how to add or edit kernel initram modules (on Arch it's obvious to do what)
Thank you
