Bug description:
  Ubuntu Desktop 16.04.6 20190222

  Test Case
  Do an entire disk installation and on the 'Who are you' page select "encrypt home", reboot and log in from lightdm

  Actual Result
  The log in is rejected. There are permission denied in the logs (journal attached)

  This is a *regression* in 16.04.6. It works fine on 16.04.5.

  The following message appears in the logs:
  """"
  user-setup: Error: Your kernel does not support filename encryption
  user-setup: ERROR:  Could not add passphrase to the current keyring
  user-setup: adduser: `/usr/bin/ecryptfs-setup-private -b -u u' returned error code 1. Exiting.
  """"

  This is with kernel 4.15.0-45-generic
  16.04.5 uses kernel 4.15.0-29-generic
