Ubuntu: fully disabling cryptswap

I wanted to disable cryptswap on my PopOS (an Ubuntu derivative). - Used mkswap to re-initialize the swap partition - Edited /etc/fstab to directly reference it (as opposed to a crypto device) - Removed the now non-existent crypto partition from /etc/crypttab - Ran sudo cryptsetup remove cryptswap And yet, every time I boot, the system waits for a few seconds for the now non-existent encrypted swap partition to become available. Seems like there is some remaining configuration which I have not removed. What is it and how do I remove it completely?
