This is because the raspi2 kernel package does not Provides: zfs-dkms,
zfs-modules, as expected for Ubuntu kernel packages which include ZFS
support. So if you try to install the zfs-initramfs package, apt will
try to pull in something which satisfies the dependencies if nothing
else is already installed which does, and it doesn't know that the
kernel image it's pulling is not an appropriate provider of zfs for the
running system.
If there is a bug here, it's that the Ubuntu zfs sauce patches are not
enabled on the raspi2 arm64 kernel build.
However, given the memory limitations of the raspi3 family of devices,
I'm not sure it's at all advisable to try to run zfs on such a system.
