[Bug 2114780] Re: On 24.04.2 Desktop image, subiquity failed to install OEM kernel on certified systems with OEM metapackages included

[Yao Wei]

With Ubuntu Desktop 24.04.2 image, downloading and extracting ubuntu-
desktop-bootstrap revision 318, changing the related code from

kernel_model.metapkg_name_override = flavor_to_pkgname(
    pkg.name, dry_run=self.app.opts.dry_run
)

to

kernel_model.metapkg_name_override = flavor_to_pkgname(
    "oem", dry_run=self.app.opts.dry_run
)

then starting the service with "snap try", I can finish the installation
on XPS 13 9340 offline, as it is pointed to the OEM kernel correctly.

Bug description:
  On certified systems, subiquity could find a oem metapackage for the
  system, but it uses the name as part of kernel metapackage name as a
  whole (e.g. linux-oem-somerville-treecko-meta-24.04 instead of linux-
  oem-24.04), and failed to install kernel, as seen in
  /var/log/installer/curtin-install/subiquity-curthooks.conf

  kernel:
    package: linux-oem-somerville-treecko-meta-24.04

  ubuntu-desktop-provision 0+git.6ada1bd52, rev 324

  Log files under /var/log/installer are attached.
