zfs-2.1.7 dkms fails to install on Fedora 36
System information
| Type | Version/Name |
|---|---|
| Distribution Name | Fedora |
| Distribution Version | 36 |
| Kernel Version | 6.0.10-200.fc36 |
| Architecture | x86_64 |
| OpenZFS Version | 2.1.7 |
Describe the problem you're observing
Installing and or reinstalling does not work because during the installation of zfs-2.1.7 /var/lib/dkms/zfs/2.1.5/source/dkms.conf is missing. Note the different versions (2.1.5 vs. 2.1.7)
Error! Could not locate dkms.conf file.
File: /var/lib/dkms/zfs/2.1.5/source/dkms.conf does not exist.
Describe how to reproduce the problem
sudo dnf reinstall zfs zfs-dkms

I've run into this several times in the past. It seems to happen if zfs-dkms and the kernel are updated in the same transaction. Maybe the RPM hooks are running in the wrong order?
I've been able to prevent it from happening by doing updates in two transactions:
# All updates, including zfs, but excluding the kernel
sudo dnf update --exclude kernel\*
# Just the kernel
sudo dnf update
If it's already in the broken state, I've taken the nuclear option in the past:
sudo rpm -e --nodeps zfs-dkms
sudo rm -r /var/lib/dkms/zfs/<leftover old version>
sudo dnf install zfs-dkms
Am I mistaken, or can DKMS only build against the current Kernel? Because this is what happens: The recompilation hook fires during the transaction. Yesterday during the update, a lovely module for 2.1.7/6.0.9 was created, while the Kernel prepped itself to be at 6.0.10. with the next reboot. Before uninstall, this module version was ACTIVE on this kernel.
As the DKMS build ultimately worked, this feels like a packaging question around Fedoras RPMs and how DNF resolves the dependencies during the module build triggers, some kind of race condition of active and newly installed Kernels, ZFS package versions, and at what time a compilation is fired. We've seen that kind of behaviour with ZFS RPM package updates many times over the last years. Would there be some kind of dnf trigger, like the system upgrade code path, which could rebuild the module during the first boot into the new Kernel?
For Fedora, similar behaviours are also observed on Silverblue:

I believe we can close here, now that subsequent versions with Fedora 36 support had been released.
