I'm trying to create a LUKS LVM disk partition autmatically using preseed on Debian 10 (Buster). I have only a single disk /dev/sda with the size of 80GB and it has system memory of 4GB
Here is my full preseed configuration:

The other preseed config ran successfully. The disk is created with LUKS LVM but the problem is that there is a missing partition like /home (which is not created from the beginning) but I did defined it in the preseed file above. In addition, the swap disk space should be 4GB but it filled up the rest of the space. Here is the screenshot how this preseed config created the disk structure:
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 79G 0 disk
|-sda1 8:1 0 976M 0 part /boot
|-sda2 8:2 0 1K 0 part
`-sda5 8:5 0 78G 0 part
`-sda5_crypt 254:0 0 78G 0 crypt
|-box1-root 254:1 0 14.3G 0 lvm /
|-box1-tmp 254:2 0 1.9G 0 lvm /tmp
`-box1-swap 254:3 0 61.8G 0 lvm [SWAP]
What could be the reason for this? Any mistakes in my preseed file for partitioning?
My partition scheme is this:
TOTAL SPACE is 80 GB
partition: /boot 1GB | FILE SYSTEM: ext4 | bootable flag: on | no need to encrypt
# This is LVM container encryption called box1:
partition: /root (/) 15 GB | FILE SYSTEM: ext4
partition: /tmp 2GB | FILE SYSTEM: ext4 | mount with: nosuid, noexec
partition: swap 4GB
partition: /home 60GB (or the rest space left) | FILE SYSTEM: ext4| mount with: nosuid
40960 61440 -1for the /home partition (minimum 40GB, "priority" 60GB, maximum unlimited). With a total size of 80GB, your80896 80896 1000000is asking for a minimum size of 80GB for /home, after all the other partitions have been defined....at a guess, this may be what is confusing di-partman.40960 61440 -1I still don't get the home partition created and it's the similar result that I posted in the question. Something is wrong here. I'm not sure where, I've been looking for this for many hours now. Do you know how to debug this error after Debian installation?
