Public bug reported:
I had fresh install of Ubuntu 24.04 with ZFS and a 8GB swap partition
automatically made by the Ubuntu installer, as /dev/nvme0n1p3.
I upgraded to 24.10 and the swap is not available after reboot. It seems
swapon cannot find the encrypted partition. What went wrong during the
upgrade?
My /etc/fstab is unmodified since the fresh install:
# /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/disk/by-id/dm-uuid-CRYPT-PLAIN-dm_crypt-0 none swap sw 0 0
# Use `zfs list` for current zfs mount info
# bpool none defaults 0 0
# Use `zfs list` for current zfs mount info
# rpool none defaults 0 0
# Use `zfs list` for current zfs mount info
# rpool / defaults 0 0

# Use `zfs list` for current zfs mount info
# bpool /boot defaults 0 0
# /boot/efi was on /dev/nvme0n1p1 during curtin installation
/dev/disk/by-uuid/6DA7-371B /boot/efi vfat defaults 0 1
And my /etc/crypttab:
dm_crypt-0 PARTUUID=d5018485-33be-40b8-80a1-9adb3c96ff16 /dev/urandom
swap,initramfs
In /etc/crypttab I tried to replace the ID
PARTUUID=d5018485-33be-40b8-80a1-9adb3c96ff16 by /dev/nvme0n1p3 but it didn't
solve the problem after rebooting.
I also tried to add these options:
swap,initramfs,plain,cipher=aes-xts-plain64,size=256

Also, I don't know if it is related but during boot, when prompted for
the (ZFS encrypted) disk password, I have the following warning:
cryptsetup: WARNING: Option 'size' missing in crypttab for plain dm-
crypt mapping dm_crypt-0. Please read /usr/share/doc/cryptsetup-
initramfs/README.initramfs.gz and add the correct 'size' option to your
