[LU-17018] Unable to install DKMS on Ubuntu client

Blocker — Wed, 6 Sep 2023 12:31:38 +0000

Trying to install the dkms client modules on a Ubuntu 22.04 node. APT complains about:

The following packages have unmet dependencies:
 lustre-client-modules-dkms : Depends: linux-image (>= 3.10) or
                                       linux-image-amd64 (>= 3.10) but it is not installable or
                                       linux-image-arm64 (>= 3.10) but it is not installable

This is due to a change in ~~LU-16661~~ causing issue with Ubuntu as it doesn't have the "linux-image" package installed but the "linux-image-generic" one.

"linux-image-*-generic" does provide the "linux-image" package:

Description: Signed kernel image generic
 A kernel image for generic.  This version of it is signed with
 Canonical's signing key.
Built-Using: linux (= 5.15.0-78.85)

But this field is ignored when "Depends" is versioned as stated in the Debian policy manual

If the Provides field does not specify a version number, it will not satisfy versioned dependencies or violate versioned Conflicts or Breaks.

Could we add the "linux-image-generic" package in the dkms dependency in addition to the existing "linux-image*" one in "debian/control"?
