Comment 20 for bug 1453738

@danny: thanks, so this confirms the issue. Please either drop /etc/crypttab if you want to keep the unencrypted swap, or drop /dev/mapper/ubuntu--vg-swap from /etc/fstab and uncomment #/dev/mapper/cryptswap1. You can't have both. Do you still know how you set that up? In particular, whether you wrote /etc/fstab in that way, or it was set up by some tool? Thanks!
