Hi Bryan,

I agree, that it would be better if this issue is resolved. The
work-around to swapoff the zRAM is not too difficult, but of course, the
zRAM should be tolerated during the installation.

sudo swapoff -a

See the attached very early suggestion to a testcase for the Lubuntu
desktop installer

Best regards
Nio

Install (entire disk with LVM and encryption) in Lubuntu Desktop i386/amd64 
You are currently on: Lubuntu ISO Testing

Link to the download information [modify link for lubuntu desktop i386 and amd64]
Detailed information on the testcase [give it a new number]
Link to bug reporting instructionsHide Testcase
Proceed in your native language if you wish. Instructions will remain in English
Boot up the image 
The system boots properly and loads the installer displaying Welcome dialog with language selection and 'Try Lubuntu' and 'Install Lubuntu' lines
Select the the Try Lubuntu line and press the Enter key
Wait until the desktop is displayed.

Start a terminal window and run the following commands

##### start block that is only necessary if you try to install encrypted home #####

Wipe the partition table (at least this dangerous step should be merged into the installer)

Identify the drive, where you intend to install the encrypted Lubuntu system with the command

sudo parted -l

It is often but not always the first hard disk drive /dev/sda

Now wipe the target drive's first megabyte

sudo dd if=/dev/zero of=/dev/sdx bs=1024 count=1024

or much safer if manually with mkusb

Then write an MSDOS partition table  with gparted

sudo -H gparted

Select the menu option

Device – Create Partition Table (and use the default option 'msdos')
Click on 'Apply' and exit from Gparted.

Continue in the terminal window.

sudo partprobe

If partprobe complains, please reboot the computer! After a reboot check that there is an MSDOS partition table and no partitions. In that case you can skip to here (and start to shut off swap). Else (if partprobe is happy) continue.

##### end block that is only necessary if you try to install encrypted home #####

Shut off the zRAM (can be merged into the installer, and is not dangerous)

swapon -s

You will see zRAM, which will confuse the installer and must be shut off with the following command

sudo swapoff -a

Check that there is no swap now with

swapon -s

Close close the terminal window.

Start the installer (double-click on the 'Install Lubuntu' icon on the desktop)
Wait until the 'Install' screen with Welcome is displayed, select language (again) and press the 'Continue' button
