[Bug 2046198] Re: webcam not working on XPS 9320 with Ubuntu 22.04.3

[jeremyszu]

So here are total three topics in the installer/images:

1. linux-modules-ipu6/ivsc (and future usbio) are not in image (CDROM)
and def install_extras() only install packages from CDROM even if users
perform online installation.

2. installer needs an extra `ubunut-drivers list` to detect if any
packages (With modaliase) from oem archive are required for this
platform. A potential fix:
https://git.launchpad.net/~os369510/ubiquity/commit/?id=ff333f4013ecbc6fe662bca4ff8d7f2657497473,
which could solve the potential bug report (i.e. my wireless doesn't
work, because it needs backport-iwlwifi-helper from oem-archve) in the
future.

3. apt install ${oem-meta} (when upgrading it from def install_extras()) will fail if "XB-Ubuntu-OEM-Kernel-Flavour" points to "oem" because only linux-oem-22.04 in the CDROM (iso) but the real oem meta packages require linux-oem-22.04{d,+} but linux-oem-22.04 points to "linux-oem-22.04c".
I'm wondering if we can get updates from ubuntu-archive in def install_extras().

Bug description:
  Hi,

  I installed Ubuntu 22.04.3 on XPS 9320 (came with Windows pre-
  installed). Both "HAL library for MIPI Camera through Intel IPU6 by
  libcamhal0" and "hardware support for Dell XPS 13 9320 by oem-
  somerville-tentacool-meta" were automatically activated after install.
  Webcam however was not detected

  I saw bugs #2039471 and #2039746, and followed what's suggested there
  but to no avail. Camera is detected now but gives a black image (0
  FPS).
