I'm using the official Arch liveimage, downloaded yesterday. It is possible the Kernel just got upgraded in the repositories.
> Installing zfs-utils and zfs-linux
warning: zfs-utils-2.2.0-1 is up to date -- reinstalling
warning: cannot resolve "linux=6.5.9.arch2-1", a dependency of "zfs-linux"
error: failed to prepare transaction (could not satisfy dependencies)
My Kernel version on the live image is the above, but it is not available in the repositories anymore:
# uname -a
Linux archiso 6.5.9-arch2-1 #1 SMP PREEMPT_DYNAMIC Thu, 26 Oct 2023 00:52:20 +0000 x86_64 GNU/Linux
