[Pkg-zfsonlinux-devel] Bug#1024326: bullseye to bookworm upgrade failure: Could not locate dkms.conf file

[Antoine Beaupre]

Package: zfs-dkms
Version: 2.1.6-3
Severity: serious

I have tried to upgrade to bookworm today and kernel builds fail on
zfs-dkms. It fails with:

dkms: running auto installation service for kernel 6.0.0-4-amd64:Error! Could not locate dkms.conf file.
File: /var/lib/dkms/zfs/2.0.3/source/dkms.conf does not exist.

It's odd because zfs 2.0.3 is gone now... The package has been
upgraded at this point... Yet the /var/lib/dkms/zfs/2.0.3 directory
was still around. Removing it fixes the problem:

    rm -rf /var/lib/dkms/zfs/2.0.3

Note that I am doing batch upgrades with a special procedure, with
this command:

    env DEBIAN_FRONTEND=noninteractive APT_LISTCHANGES_FRONTEND=none APT_LISTBUGS_FRONTEND=none UCF_FORCE_CONFFOLD=y \
        apt full-upgrade -y -o Dpkg::Options::='--force-confdef' -o Dpkg::Options::='--force-confold' &&

... which might have cause the old directory to not be removed.

See this for my upgrade procedure:
