Public bug reported:

The modules-extra packages for derivative kernels (maybe just some of
them) do not get installed during ADT testing, despite what looks like
an attempt to do so with this setup-command:


--setup-commands 'apt-get install -y ^kernel-testing--linux\-aws\-6\.5--modules-extra--preferred$ || apt-get install -y ^linux-modules-extra\-aws\-6\.5$ || :'

This results in nothing being found:

When testing linux-generic, the modules-extra package is installed as a
result of a dependency from linux-image-generic:

$ apt-cache show linux-image-generic
…
Depends: linux-image-5.15.0-105-generic, linux-modules-extra-5.15.0-105-generic, linux-firmware, intel-microcode, amd64-microcode

But the aws kernel is different:

$ apt-cache show linux-image-aws
…
Depends: linux-image-6.5.0-1018-aws, microcode-initrd
$ apt-cache show linux-image-6.5.0-1018-aws
…
Depends: kmod, linux-base (>= 4.5ubuntu1~16.04.1), linux-modules-6.5.0-1018-aws

The only thing which depends on the modules-extra package, is what looks
like a meta package: 

$ apt-cache rdepends linux-modules-extra-6.5.0-1018-aws
linux-modules-extra-6.5.0-1018-aws
Reverse Depends:
  linux-modules-extra-aws
  linux-modules-extra-aws-edge
$ apt-cache rdepends linux-modules-extra-aws
linux-modules-extra-aws
Reverse Depends:
$ apt-cache rdepends linux-modules-extra-aws-edge
linux-modules-extra-aws-edge
Reverse Depends:

This meta package does contain a “Provides”, but it does not match what the ADT setup command is trying to install:
$ apt-cache show linux-modules-extra-aws
Package: linux-modules-extra-aws
…
Provides: kernel-testing--linux-aws-6.5--modules-extra--aws
Depends: linux-modules-extra-6.5.0-1018-aws

The difference is `^kernel-testing--linux-aws-6.5--modules-extra--
preferred$` vs `kernel-testing--linux-aws-6.5--modules-extra--aws`

I do not have a list of kernels that show this behavior. Just looked at
focal:linux-aws-5.15, focal:linux-azure-5.15 and jammy:linux-aws-6.5
(and compared with the behavior of jammy:linux)
