Unable to receive ZFS snapshots from Debian system with zfs-2.0.3-9: kernel modules must be upgraded to receive this stream

Asked by Robin

The receiving system:

# zfs --version
zfs-2.1.2-1ubuntu3
zfs-kmod-2.1.2-1ubuntu3
# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 22.04 LTS
Release: 22.04
Codename: jammy
# uname -a
Linux server 5.15.0-27-generic #28-Ubuntu SMP Thu Apr 14 04:55:28 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

The sending system:
# zfs --version
zfs-2.0.3-9
zfs-kmod-2.0.3-9

# lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description: Debian GNU/Linux 11 (bullseye)
Release: 11
Codename: bullseye

# uname -a
Linux server 5.10.0-13-amd64 #1 SMP Debian 5.10.106-1 (2022-03-17) x86_64 GNU/Linux

When doing a raw send/receive using the following command:
syncoid --mbuffer-size=1M --target-bwlimit=1m --source-bwlimit=1m --sendoptions=w root@othersystem:somepool/somedataset somepool/somedataset

I get the following error message:
cannot receive incremental stream: kernel modules must be upgraded to receive this stream.

However, the kernel modules on the receiving system are more recent than those on the target system? The source dataset does not use encryption, the target dataset does.
