Can't encrypt home, says "Error Cannot Proceed"

Question

I recently installed lubuntu 17.10.1. When I attempted to encrypt the home folder during the installation, it wouldn&#39 t encrypt it. It kept saying something about &#39 swap space&#39 , like &quot An unsafe swap space has been detected&quot . It wouldn&#39 t let me encrypt it.

So I&#39 m attempting to encrypt it after the fact. I&#39 m following the instructions here: https://websiteforstudents.com/encry...-ubuntu-17-10/

I managed to create the octopus account and tried to continue with step 3. But it tells me &quot ERROR: Cannot proceed&quot .

Where it says sudo ecryptfs-migrate-home -u USER
in the instructions, I entered octopus instead of USER. It said ERROR Cannot proceed. So I tried it again with my real username. Got the same ERROR message.

I have attempted sudo ecryptfs-migrate-home -u USER in both accounts.

Why does it say ERROR, and what am I supposed to do to solve this?

Looks like you've chosen full disk encryption, but kept an unencrypted swap partition .. you need to use:
sudo ecryptfs-setup-swap
