That says Swap:   0        0       0

The result of cat/etc/fstab  is:
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type> <options>       <dump>  <pass>
/dev/mapper/ubuntu--vg-root /               ext4 errors=remount-ro 0       1
# /boot was on /dev/sda1 during installation
UUID=ba8d370e-f29c-4c18-ae93-650b7fe5f2a2 /boot           ext2 
defaults        0       2
/dev/mapper/cryptswap1 none swap sw 0 0

Output of blkid:

/dev/sda1: UUID="ba8d370e-f29c-4c18-ae93-650b7fe5f2a2" TYPE="ext2"

/dev/sda5: UUID="f114109b-288a-432e-85bb-ba6be511ad58" TYPE="crypto_LUKS"

/dev/mapper/sda5_crypt: UUID="GVodJX-Am7J-fDKW-PWoG-7XBA-LpvG-U3G5NB" 
TYPE="LVM2_member"

/dev/mapper/ubuntu--vg-root: UUID="c0f919a1-e626-44d6-b621-73134eeefda4" 
TYPE="ext4"
