The correct way to disable the warning seems to be to add
RESUME=none
to /etc/initramfs-tools/conf.d/resume
if your swap has a /dev/urandom key.

Upgrades to 21.04 (from a 20.04 fresh install) and the warning is still
showing up

Title:
Warning message about cryptsetup during boot
To
We linked to the same discussion on askubuntu.com (I replied you there).
My hope when reporting this is that we don't have to do the workaround
you described after each kernel update.
Did you open another bug report ? In this case, I will mark this one as
a duplicate.
** Description changed:
similar problem has been reported by many other ubuntu users, myself
included.
The current solution afaik is:
sudo swapoff -a
sudo update-initramfs -c -k all
sudo swapon -a
