Custom Partitioning is deactivated

[rlgould]

I'm trying to install Kubuntu 24 as a physical machine with:

1. UEFI partition (flags=boot,esp)(definitely booted in UEFI mode), 350 MiB
2. boot partition, 4 GiB
3. LUKS encrypted partition, remainder

p3, when unlocked, is a physical LVM device. It has one volume group, named "Kub". Kub has:

1. OsRoot, 32 GiB XFS
2. Homes, 100 GiB XFS
3. Var, 10 GiB XFS
4. VarLog, 10 GiB XFS
5. Tmp, 10 GiB EXT4
6. SWAP, 10 GiB none

In the Calamares installer, when I get to the manual partitioning step, the drop-down at the top shows my nvme drive and Kub VG separately, but I can select both. I set:

1. p1 to mount at /boot/efi
2. p2 to mount at /boot
3. OsRoot mount to /
4. Homes mount to /home
5. Var mount to /var
6. VarLog mount to /var/log
7. Tmp mount to /tmp
8. SWAP no mount, use as swap

I use the "keep" option and just specify the mount points. The summary page before I click "install now" shows the correct partitioning. However, when it starts "filling file systems", p1 and p2 retain their respective mount locations, but all the logical volumes are deactivated and the LUKS device is closed. The details page and all the Calamares output disappears when an error about not being able to do the grub install shows up.

What's the correct/prescribed way to perform a custom partitioning installation with LUKS encryption and LVM?

I'll comment further... I can't even get ANY LVM enabled objects configured at install time using the Kubuntu 24.04 installer..... no pvs, vgs, lvs, etc. The installer keeps crashing. I've tried everything.

Has ANYONE gotten a successful installation using the Kubuntu 24.04 installer by using "Manual partioning"?

If so, please provide details.

Better yet, anyone have a video of a successful Kubuntu 24.04 installation using Manual partioning with LVM? I've searched and found nothing as of yet...

tazmo , I'm making pencil edits to printouts of grub files to see what I need to change on startup. I'll let you know how it goes 🤣

All I use is manual partitioning when I set up my Kubuntu LTS, so I get to practice every two years

This is my scheme:

lsblk -T --output NAME,FSTYPE,LABEL,UUID,SIZE,FSAVAIL,MOUNTPOINTS
NAME FSTYPE LABEL UUID SIZE FSAVAIL MOUNTPOINTS
nvme0n1 931.5G
├─nvme0n1p1 ext4 ac5a72f4-8003-4890-8f0e-6176ee726d12 48.6G 35.5G /
├─nvme0n1p2 vfat D912-B405 301M 292.6M /boot/efi
├─nvme0n1p3 ext4 870436af-1189-421f-8240-e35613dba718 866.2G 455.9G /home
└─nvme0n1p4 swap 93e084bc-dac6-4d6e-bb72-608fbdb1ed53 16.4G [SWAP]

I DON'T do LVM. For my use case, I don't have a use for it.
