Bug description:
  SUMMARY
  =======
  During installation with "encrypt my home folder" mode, a broken /etc/crypttab gets created which defines a non-existing swap device (usually "cryptswap1") with a UUID. This will also be put into /etc/fstab. As after installation the UUID does not exist, such systems don't have any actual swap.

  UPGRADE FIX
  ===========
  An upgrade to Ubuntu 15.04 ("vivid") will detect and comment out these broken swap devices from /etc/fstab and /etc/crypttab. If you actually want  to use those, do these steps:

   - Find the swap device that was meant to be used in "sudo fdisk -l" (it should say "Linux swap" in the last column), remember the device name (something like "/dev/sda5")
   - Find the UUID in /etc/crypttab (the long alphanumeric ID after UUID=)
   - Run "sudo mkswap -U 1234... /dev/sda5", replacing "1234" with the above UUID, and /dev/sda5 with the device name from step 1.
   - Edit /etc/crypttab to append ",offset=1024" in the fourth (last) column of the cryptswap1 line; ensure that there is *no space* between the "cipher=aes-cbc-essiv:sha256" and the appended option. If there is a leading "#" in the file, remove that too.
   - If there is a leading "#" in /etc/fstab in the line starting with /dev/mapper/cryptswap1 line, remove that.
   - Run "sudo update-initramfs -u".

  
  ORIGINAL REPORT
  ===============

  Clean install of 12.04 and with encrypted home for my user. Did all
  updates and now the bootup hangs waiting for swap to become available
  and it never seems to ever finish. The 200GB SSD below is my boot
  drive and root filesystem.
