Bruno's situation is very similar:
blkid: /dev/mapper/ubuntu--vg-swap_1: UUID="f636d7ef-9405-482d-a90a-5ba67026fcfb" TYPE="swap"
fstab: /dev/mapper/ubuntu--vg-swap_1 none swap sw 0 0 /dev/mapper/cryptswap1 none swap sw 0 0
crypttab: cryptswap1 UUID=f636d7ef-9405-482d-a90a-5ba67026fcfb /dev/urandom swap,offset=1024,cipher=aes-xts-plain64
This just simply can't work.
