As some of you may know, there is bug in the installer of Lubuntu regarding full disk encryption with LVM. I have read at multiple places to use 

sudo swapoff --all

as a workaround. That does not work for me, instead of the common error message I get the following:

Autopartitioning using LVM failed because an error occurred while creating the volume group. Check /var/log/syslog or see virtual console 4 for the details.

So here is a part of /var/log/syslog that I find relevant for my problem: 

Nov  4 08:28:21 lubuntu ubiquity: /bin/autopartition-crypto: 292: /bin/autopartition-crypto: pvs: not found  
Nov  4 08:28:21 lubuntu ubiquity: /var/lib/partman/devices/=dev=sda  
Nov  4 08:28:21 lubuntu kernel: [  104.080652]  sda: sda1 sda2 sda3  
Nov  4 08:28:21 lubuntu ubiquity: /bin/autopartition-crypto: 292:   /bin/autopartition-crypto: pvs: not found  
Nov  4 08:28:21 lubuntu kernel: [  104.555330]  sda: sda1 sda2 sda3  
Nov  4 08:28:22 lubuntu partman: mke2fs 1.43.3 (04-Sep-2016)  
Nov  4 08:28:22 lubuntu partman-crypto: kernel entropy_avail: 977 bits  
Nov  4 08:28:22 lubuntu kernel: [  104.887497] NET: Registered protocol family 38  
Nov  4 08:28:29 lubuntu ubiquity: stat: cannot stat '/dev/lubuntu-vg'  
Nov  4 08:28:29 lubuntu ubiquity: : No such file or directory

I am not sure what is wrong, there seems to be some program missing. I am also going to try an installation off of the alternate installer. Can you please give my some suggestions how to fix the problem?

It's an installer bug.

Choose the "Try Lubuntu" option from the boot menu so that you get a working desktop.

Choose "start menu" -> "system tools" -> "LXTerminal"

At the console prompt, type:

sudo apt-get install lvm2

Then run the installer icon from the desktop ("Install Lubuntu 16.10").

Clearly no-one tested any installation method that uses lvm.

  • Thanks for this. At this point, I'm inclined to just use the standard Ubuntu installer, which I'm sure is much more road-tested, and install LXDE as a last step. Is there any significant difference to the end product?

    "An error occurred while configuring encrypted volumes. The configuration has been aborted." I did all the steps, including swapoff. Lubuntu 17.04, that should be installed on VMware12.

OK, it seems to be a version related bug. Using the common 16.04. Lubuntu installer is working.
