Install (entire disk with ZFS plus encryption) in Ubuntu Desktop (Legacy) amd64 in Bionic 18.04.3 (archived)

Proceed in your native language if you wish. Instructions will remain in English.

This test involves installing a fresh system with zfs + encryption, then breaking the system in a post-install test step. If the system you are installing on is important to you, and you want to preserve the zfs+encryption installed system, do not do this test.

Boot up the image

If you see the GRUB boot menu you should see the following:

'Try or Install Ubuntu'

'Ubuntu (safe graphics)'

'OEM install (for manufacturers)'

'Test memory' (only on BIOS systems)

The system boots properly and loads the installer displaying the Welcome dialog with language selection and 'Try Ubuntu' and 'Install Ubuntu' buttons

Click on the release notes hyperlink to confirm that a browser launches and you are taken to the release notes discourse page.

Click on the Install Ubuntu button

The 'Keyboard layout' screen appears

The proposed keyboard corresponds with your keyboard

Select your keyboard layout and click on Continue

The 'Updates and other software' screen is displayed

On the screen 'Updates and other software', note the availability of the following components

Available options should represent the state of your system accurately

For Mantic and later releases, the default install is a minimal install. Releases before Mantic the default is a 'full' install, complete with other apps a user might want. The new, default, install does not include these add-ons.

• (If network is available) 'Download updates while installing Ubuntu'
• (If on a 'laptop') 'Is plugged to a power source'
• 'Install third-party software...' option available

Click on the Continue button

The 'Installation type' screen is displayed

Note the state of the 'Erase disk and install Ubuntu' radio button

The 'Erase disk and install Ubuntu' radio button is selected and the 'Advanced features' button is active

Click on the 'Advanced features...' button

The 'Advanced Features' dialog is displayed

Select 'Erase disk and use ZFS'

'Erase disk and use ZFS' is selected

Check the tickbox for 'Encrypt the new Ubuntu installation for security'

Click on the 'OK' button

The dialog closes and 'ZFS selected' is displayed next to the 'Advanced features...' button

Click Continue

The "Choose a security key" slide opens

Enter your desired security key

Click on the 'Install Now' button

'Write the changes to disks' dialogue appears

Click Continue

If there is only one hard disk, skip to step 18 (On the 'Where are you?' screen...). Otherwise, on the 'Installation type' screen verify that the drive selected on the Select drive list corresponds to the drive on the chart (e.g /dev/sda)

Selected drive is displayed on the chart

Verify that the full drive space is allocated

Full drive space is allocated for installation

Click on the Install Now button

The 'Where are you?' screen is displayed

If your system is connected to the network, note the preselected timezone corresponds with your timezone and the city indicated in the text box

The timezone and city displayed match your timezone and a major city from your area

Select your timezone, and click on the Continue button

The 'Who are you?' screen appears

Input your initial user details and password admin can not be used - it is a dedicated Linux User

'Require my password to log in' is shown and selected or if 'Log in automatically' and 'require my password to log in' are shown then 'Require my password to login' is selected. If just 'Require my password to log in' is shown, having it off is the equivalent of having 'Log in automatically' on.

Name, username and password are accepted.

Continue button becomes available

Press Continue

The 'Welcome to Ubuntu' slide is displayed

The slideshow is entirely in your language

Wait for the installer to finish

An 'Installation Complete' dialog appears

Click the 'Restart Now' button

GUI is shut down, a prompt to remove media and press Enter appears

Remove the disc and press enter

The machine is rebooted

Allow the machine to reboot

The system boots properly and your passphrase works

The system loads into Ubuntu showing username selected

Upon login, open a terminal, run the following commands and verify it matches the output

$ zfs mount | sort
bpool/BOOT/ubuntu_UUID /boot
rpool/ROOT/ubuntu_UUID /
rpool/ROOT/ubuntu_UUID/srv /srv
rpool/ROOT/ubuntu_UUID/usr/local /usr/local
rpool/ROOT/ubuntu_UUID/var/games /var/games
rpool/ROOT/ubuntu_UUID/var/lib/AccountsService /var/lib/AccountsService
rpool/ROOT/ubuntu_UUID/var/lib/apt /var/lib/apt
rpool/ROOT/ubuntu_UUID/var/lib/dpkg /var/lib/dpkg
rpool/ROOT/ubuntu_UUID/var/lib/NetworkManager /var/lib/NetworkManager
rpool/ROOT/ubuntu_UUID/var/lib /var/lib
rpool/ROOT/ubuntu_UUID/var/log /var/log
rpool/ROOT/ubuntu_UUID/var/mail /var/mail
rpool/ROOT/ubuntu_UUID/var/snap /var/snap
rpool/ROOT/ubuntu_UUID/var/spool /var/spool
rpool/ROOT/ubuntu_UUID/var/www /var/www
rpool/USERDATA/root_0y7dio /root
rpool/USERDATA/u_0y7dio /home/u


Run the lsblk command and check for this line in the output:

cryptoswap 252:1 0 2.6G 0 crypt [SWAP]

Run the following command to place a file under ~:

echo "hello" > /home/$USER/hello

We're going to check for this file in a later part of this test case.

Shut down the installed system.

Using the same .iso, boot into the iso using the disk that you just completed the installation on.

Go through the grub menu and instead of installing, select "Try Ubuntu".

Open a terminal window, and enter the following:

sudo su

fdisk -l /dev/$disk # Where $disk is the disk you completed the install on.

The output should include something similar to the following:

/dev/vda1 2048 4095 2048 1M BIOS boot
/dev/vda2 4096 1054719 1050624 513M EFI System
/dev/vda3 1054720 9037823 7983104 3.8G Linux swap
/dev/vda4 9037824 13178879 4141056 2G Solaris boot
/dev/vda5 13178880 83884031 70705152 33.7G Solaris root

For the rest of this testcase, we will use vda in place of $disk.

Check for the zfs pool names:

blkid /dev/vda*

/dev/vda: PTUUID="7dd06581-4867-4632-9a90-23d9c472b039" PTTYPE="gpt"
/dev/vda1: PARTUUID="c061c581-06c1-43e2-8680-d353771bf341"
/dev/vda2: UUID="2748-996B" BLOCK_SIZE="512" TYPE="vfat" PARTLABEL="EFI System Partition" PARTUUID="f7c29e7e-687f-4cbb-a1a1-f8876f809a64"
/dev/vda3: UUID="8c1d6471-1f90-4212-8fbd-097a9a9ad909" TYPE="crypto_LUKS" PARTUUID="8ff61492-9bda-40fe-94a8-7d6fe4d220cb"
/dev/vda4: LABEL="bpool" UUID="8851209407646287070" UUID_SUB="1631837207961890120" BLOCK_SIZE="4096" TYPE="zfs_member" PARTUUID="8b8b8818-cc94-42bd-b23d-cf7c9e9b73ff"
/dev/vda5: LABEL="rpool" UUID="4519996901618382696" UUID_SUB="8860607139843727357" BLOCK_SIZE="4096" TYPE="zfs_member" PARTUUID="5cc65ba9-8ef4-475c-a107-cc130a9be1be"

Here, the zfs pool names are the labels of the drives of TYPE "zfs_member". So in this case, the zfs pools are "bpool" and "rpool".

Now, we will import the pool of the root partition:

zpool import rpool

Check the output of the following command to see that rpool is imported:

zpool status -v

After entering the following command, enter your security key in the prompt:

cryptsetup luksOpen /dev/zvol/rpool/keystore keystore

Mount the keystore:

mkdir /mnt/keystore

mount /dev/mapper/keystore /mnt/keystore

Copy the key to necessary location:

mkdir -p /run/keystore/rpool

cp -b /mnt/keystore/system.key /run/keystore/rpool

Make the root pool mountable:

zfs set canmount=on rpool

Load the zfs key:

zfs load-key rpool

Check for the pool associated with the userdata:

zfs list -o name,type,keylocation

You want to find a line in the output of the above command in this format:

$poolname/USERDATA/$username_$hash

For example: rpool/USERDATA/tim_aqj46w

Set mountpoint for USERDATA:

mkdir -p /mnt/rpool/USERDATA/tim_aqj46w

zfs set mountpoint=/mnt/rpool/USERDATA/tim_aqj46w rpool/USERDATA/tim_aqj46w

Mount the pool:

zfs mount -a

Check for the test file we made earlier, for example:

cat /mnt/rpool/USERDATA/tim_aqj46w/hello

The output should be "hello"
