  Encrypted swap does not work

Bug description:
  On a working system, i've added a new hdd, and decided to use it as the main device storage.
  So after doing the formatage (classic: / as ext4, swap, /home as ext4), i've set a bionic iso installation.
  Ubiquity then have proposed to set an encrypted swap dir, which i have accepted, and then smootly terminated the installation.

  Booting with that new install, i hit a cryptswap1 timeout after beeing
  frozen around 1 minute.

  oem at ubuntu:~$ journalctl | grep cryptswap
  systemd[1]: Starting Cryptography Setup for cryptswap2...
  systemd[1]: Started Cryptography Setup for cryptswap2.
  systemd[1]: Found device /dev/mapper/cryptswap2.
  systemd[1]: Activating swap /dev/mapper/cryptswap2...
  kernel: Adding 10584572k swap on /dev/mapper/cryptswap2.  Priority:-1 extents:1 across:10584572k FS
  systemd[1]: Activated swap /dev/mapper/cryptswap2.
  systemd[1]: Starting Cryptography Setup for cryptswap1...
  systemd[1]: Started Cryptography Setup for cryptswap1.

  oem at ubuntu:~$ journalctl | grep timeout
  systemd[1]: dev-disk-by\x2duuid-4c8437f6\x2d677d\x2d4740\x2dbdda\x2d072efadb49f4.device: Job dev-disk-by\x2duuid-4c8437f6\x2d677d\x2d4740\x2dbdda\x2d072efadb49f4.device/start failed with result 'timeout'.

  Note: cryptswap2 refer to the new hdd's swap partition, cryptswap1 refer to the old hdd's swap partition.
  /etc/fstab have been tested with only the active (mounted) disk, and with both. In both cases the timeout happens.

  oem at ubuntu:~$ swapon -s
  Filename				Type		Size	Used	Priority
  /dev/dm-0                              	partition	10584572	221184	-1

  
  Conclusion:
  -ubiquity is proposing a non working feature (at least with multiple storage devices/swap partitions
  - the cryptsetup version is not well supporting the kernel/systemd settings/configs

  As Debian has more recent versions: 1.7.5-1 (sid) and 2.0.0 (experimental) with some new features and cleanups, it should be a positive test to replace the actual not working version with one of these.
