Title:
  Failed to start Cryptography Setup for cryptswap1

Status in cryptsetup package in Ubuntu:
  Confirmed

Bug description:
  Fresh install of 17.10.  On first boot, after install, there were no
  issues; the desktop booted fine.  I then ran an `apt upgrade`, set my
  home encryption passphrase and rebooted.  Now, after typing my
  password, rather than Gnome starting, I get systemd errors:

  Failed to start Cryptography Setup for cryptswap1
  Dependency failed for dev-mapper-cryptswap1.device
  Dependency failed for /dev/mapper/cryptswap1

  If I wait long enough, I get the gdm3 login window again.  If I try to
  log in after this, I get the Gnome desktop without any issue.
