Swap: From partition to file, now get “no matching swap device is available”

Running Ubuntu 18.04, I changed from a swap partition to a swap file.

swapon -s (summary) and free show the swapfile with the new size. /etc/fstab was changed, permission on the swapfile changed and the swap partition was deleted. When there are updates (apt-get update and upgrade), I get this error:

Setting up amd64-microcode (3.20180524.1~ubuntu0.18.04.2) ...

update-initramfs: deferring update (trigger activated)

amd64-microcode: microcode will be updated at next boot

Processing triggers for libc-bin (2.27-3ubuntu1) ...

Processing triggers for initramfs-tools (0.130ubuntu3.1) ...

update-initramfs: Generating /boot/initrd.img-4.15.0-29-generic

W: initramfs-tools configuration sets RESUME=UUID=c5a2c6f4-b67c-4d95-bc23-8333ed6c0f11

W: but no matching swap device is available.

The UUID listed there is for the old swap partition. I didn't think a swap file has a UUID, but I am not sure about that. Everything else seems to work fine. How should I proceed to troubleshoot and fix this?

What does this show? sudo swapon --show? And: ls -lh /swapfile

outputs are: NAME TYPE SIZE USED PRIO /swapfile file 3G 0B -2 and -rw------- 1 root root 3.0G Jul 10 13:00 /swapfile

Those look essentially the same as mine. What does fstab show? Post above to preserve formatting. cat /etc/fstab

Tried to post it above, but text was huge. Just going to put the last lines (about swap) here: # swap was on /dev/sdb5 during installation #UUID=c5a2c6f4-b67c-4d95-bc23-8333ed6c0f11 none swap #sw 0 0 # swap now in /swapfile /swapfile none swap sw 0 0
