Kubuntu Installation

Installation

Follow installations step normally and select full disk encryption if needed.

Moving home to own partition

When installing Ubuntu from scratch you get the option to use full disk encryption using LUKS and LVM, but it doesn't give you the option of specify your own partition layout; it creates a small swap partition and gives the rest to the root partition. The easiest way is to let the Ubuntu installer do it's thing and then resize the root partition and add a home partition afterwards. This is complicated by the use of LUKS to encrypt the disk and it’s not possible to resize a root partition while it’s in use.

The following assumes that:

The encrypted partition is /dev/nvme0n1p3
The LVM volume group is called vgkubuntu
The root partition will use 100 GB of space
The home partition will use the rest of the free space on the disk

Boot off the Ubuntu install medium.
Decrypt the disk and mount the encrypted LUKS partition.

bash

sudo cryptsetup luksOpen /dev/nvme0n1p3 vgkubuntu-vg

sudo cryptsetup luksOpen /dev/nvme0n1p3 vgkubuntu-vg

Resize the root partition to 100 GB.

bash

sudo e2fsck -f /dev/mapper/vgkubuntu-root
sudo resize2fs /dev/mapper/vgkubuntu-root 90G
sudo lvreduce -L 100G /dev/mapper/vgkubuntu-root
sudo resize2fs /dev/mapper/vgkubuntu-root

sudo e2fsck -f /dev/mapper/vgkubuntu-root
sudo resize2fs /dev/mapper/vgkubuntu-root 90G
sudo lvreduce -L 100G /dev/mapper/vgkubuntu-root
sudo resize2fs /dev/mapper/vgkubuntu-root

create a new home partition using all the free disk space

bash

sudo lvcreate -n home -l 100%FREE vgkubuntu
sudo mkfs.ext4 /dev/mapper/vgkubuntu-home

sudo lvcreate -n home -l 100%FREE vgkubuntu
sudo mkfs.ext4 /dev/mapper/vgkubuntu-home

Copy everything off the home directory on the root partition into the new home partition.

bash

mkdir /root
sudo mount  /dev/mapper/vgkubuntu-root /root
mkdir /home
sudo mount  /dev/mapper/vgkubuntu-home /home
rsync -av root/home/ home/

mkdir /root
sudo mount  /dev/mapper/vgkubuntu-root /root
mkdir /home
sudo mount  /dev/mapper/vgkubuntu-home /home
rsync -av root/home/ home/

Edit the /root/etc/fstab file in the mounted root partition and add the following:

/dev/mapper/vgkubuntu-home	/home		ext4	defaults	0	2

/dev/mapper/vgkubuntu-home	/home		ext4	defaults	0	2

Unmount the drives and reboot

bash

sudo umount /root
sudo umount /home
sudo reboot

sudo umount /root
sudo umount /home
sudo reboot

And if all went well you have moved home onto it’s own partition.
