Interesting.  So where does this come from?
https://launchpad.net/~ubuntu-concept/+archive/ubuntu/x13s points to
https://code.launchpad.net/~ubuntu-concept/+recipe/ubuntu-concept-x13s
which 404s.

> XB-Task: ubuntu-live, ubuntu-desktop, ubuntu-desktop-minimal

Oh please no.  For one thing, we shouldn't need this anymore now that
livecd-rootfs calls germinate directly.  For another thing, 'ubuntu-
live' is not a correct task name that appears anywhere in the archive.
And thirdly, these packages shouldn't be injected into the platform-
independent tasks.

> Package: ubuntu-concept-x13s

Immediately I notice this uses a completely different structure to
what's used on raspberry pi.  We should have a think about how to handle
platform metapackages consistently in the archive.

Also I have no idea why 'concept' appears in the package name here, it
appears to be a reference to the PPA name only and has nothing to do
with the hardware platform branding.

Title:
  [FFe] Build and release ubuntu desktop arm64 x13s image on
  cdimage.ubuntu.com

Status in livecd-rootfs package in Ubuntu:
  Triaged

Bug description:
  [FFe] Build and release ubuntu desktop arm64 x13s image on
  cdimage.ubuntu.com

  PPA ~ubuntu-concept/x13s contains a kernel that supports all expected
  laptop/desktop features.

  It boots, it has accelerated GPU, Wifi works, it has Bluetooth,
  Fingerprint scanner works, Touchscreen works, UEFI firmware variables
  work, one can open firefox and watch cat videos.

  All firmware blobs are publically redistributable and have been
  contributed upstream by the hardware vendor.

  Outstanding issues are cleaning up kernel patches and integrating them
  in generic kernel that hopefully can be completed next cycle.

  There is no support yet for Secureboot or Camera. But work is in
  progress to get those things done as well.

  Please enable building Ubuntu Concept image on the cdimage.ubuntu.com
  instance, and release it as part of the regular Ubuntu release cycle
  with .iso signed by the Ubuntu Cdimage key and downloadable from
  ubuntu.com

  The following modifications will be required on livecd-rootfs:

  * agree subarch name, proposed "x13s"
  * enable ubuntu concept ppa
  * install ubuntu-concept-x13s meta package
  * use linux-laptop kernel flavour
  * extract dtb from squashfs and tweak grub.cfg on the iso to load it by default

  If there is agreement and guidance on the above, I can swiftly
  implement this, land, and test all builds.

  There are over 4 people in the company with the required hardware, and
  a wider community of users that can also contribute to testing this
  image.

  In 24.04 I hope that linux-laptop changes can all be upstreamed to the
  generic kernel, to release Ubuntu Desktop generic iso on arm64
  targetting X13s & VM usage, plus any other generic arm64
  server/desktop platforms.
