Hi, `zfs-dkms` package's module-building process on Armbian-ubuntu-noble has been unsuccessful with recent versions of the linux-current-meson64 kernel/headers/dtb that is higher than `26.5.1` (I'm not sure if `26.5.1` is the highest version that works with `zfs-dkms`; there might be a working version higher than `26.5.1`, but my fail-safe version has been this one.) Can someone help me keep updating linux kernel without breaking zfs-dkms? I attach the output of `apt` just in case: ```sh $ sudo apt install linux-image-current-meson64 Reading package lists...

Today I realized a higher version of zfs-dkms(2.4.1) was actually offered in the Armbian repository. So I entered the command below to upgrade zfs-dkms to 2.4.1 and it was successful:

The same issue has occurred again. I had to take this measure again today to fix the zfs module. I had to revert the kernel, headers and dtb back to 25.11.2 from 26.2.1 of linux(meson64:arm64)

I don't want to take that measure..

The new kernel version was `6.12.55` and the previous one was `6.12.44`

Some modules are not included in the kernel package by default. In my case I had to install zfs-dkms built upon Dynamic Kernel Module Support(DKMS). The module gets rebuilt whenever I upgrade the kernel—I'm not sure exactly which package I have to upgrade first though, header? dtb? Somehow the zfs module was not successfully built after I upgraded the kernel, its header files, and the device tree blobs.

I don't think that's a relevant issue. I couldn't `modprobe zfs` in my case.

Version `25.8.2` of kernel, dtb and/or header package on Armbian Ubuntu Noble break `zfs-dkms` (I'm pretty sure kernel module `zfs` was not built with success) I had to run: ```sh sudo apt install linux-image-current-meson64=25.8.1 linux-headers-current-meson64=25.8.1 linux-dtb-current-meson64=25.8.1 && sudo dpkg-reconfigure zfs-dkms ``` I couldn't look in to the problem, because I was busy doing something else when I was just upgrading every package on the system. I had to prioritize quickly fixing it before another user arrives so I just reverted the suspicious packages (the three I mentioned in the title) I can't look into the problem now either because the computer is not being used by me alone..

The repository hasn't changed the inventory of zfsutils-linux and zfs-dkms for several days. I guess there is some kind of problem? https://repo.jing.rocks/armbian-apt/dists/jammy/jammy-utils/binary-arm64/Packages

I see that the merged commit is reflected in the nightly beta repository of `jammy-utils` When would it make its way into the stable repository? $ cat Packages ...

I guess you read the next major version number (6) of `libzpool` and `libzfs` on Ubuntu 25.04 (Plucky) then.. I see

Awesome! I have very little knowledge.. but now that you have showed me how to fix `zfsutils-linux` by bumping up the version numbers for its dependencies I can try to fix a similar problem in the future. I wonder how you figured out `libzfs[[:digit:]]linux` and `libzpool[[:digit:]]linux` were preventing the update of `zfsutils-linux`; That skill will come in handy!

I think the solution is on its way to Armbian Jammy

I believe we need to contact the maintainer of `http://apt.armbian.com jammy-utils` so that they can synchronize the versions of these packages: linux-dtb-current-meson64 linux-headers-current-meson64 linux-image-current-meson64 zfs-dkms zfsutils-linux Any contact information? I don't really want to build zfsutils-linux 2.2.7 myself.

It turns out the old version of zfs-dkms from /etc/apt/sources.list.d/zfs.list has never been used. --Should I keep it, not deleting it? o-hc4-01:~:% apt show zfs-dkms Package: zfs-dkms Version: 2.2.7-0arter97~ubuntu22.04.1 Priority: optional Section: contrib/kernel Source: zfs-linux Maintainer: Ubuntu Developers <ubuntu-devel-discuss@lists.ubuntu.com> Original-Maintainer: Debian ZFS on Linux maintainers <pkg-zfsonlinux-devel@alioth-lists.debian.net> Installed-Size: 18.1 MB Provides: zfs-modules Depends: dkms (>> 2.1.1.2-5), file, libc6-dev | libc-dev, lsb-release, python3-setuptools | python3-distutils | libpython3-stdlib (<< 3.6.4), debconf (>= 0.5) | debconf-2.0 Recommends: zfs-zed, zfsutils-linux (>= 2.2.7-0arter97~ubuntu22.04.1), linux-libc-dev (<< 6.13~), linux-libc-dev (>= 4.18~) Suggests: debhelper Breaks: spl-dkms (<< 0.8.0~rc1) Replaces: spl-dkms Homepage: https://zfsonlinux.org/ Download-Size: 2,443 kB APT-Sources: http://apt.armbian.com jammy/jammy-utils arm64 Packages Description: OpenZFS filesystem kernel modules for Linux N: There are 6 additional records.

The original maiintainer of the the launchpad repository passed away on January 7, 2023 I have no idea who uploaded the recent versions of zfs-dkms for jammy, and whom I should report about the bug.

I've filed a bug report on Ubuntu: https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/2102870 EDIT: i actually had to send a report to the author of the actual apt repository: https://launchpad.net/~jonathonf/+archive/ubuntu/zfs

the version number of zfsutils-linux was too low for the new version of zfs-dkms. So I downgraded zfs-dkms but the recent version of linux kernel was too high for the old version of zfs-dkms. I tried armbian-config to change the version of the kernel down to 6.6 from 6.12.18 but somehow it just repeatedly tried to build dkms modules for 6.12.18 again and again so I just gave up using armbian-config. I eventually replaced the linux kernel and headers with the older version 24.8.2 ( sudo apt install linux-image-current-meson64=24.8.2 linux-headers-current-meson64=24.8.2 linux-dtb-current-meson64=24.8.2 ) After these downgrades ZFS started working fine.
