Public bug reported:
[ Description ]
If a piece of hardware is enabled after the latest Ubuntu release is
created, it is not found by the installer and so people who install
Ubuntu do not get its extra hardware enablement.
The information the installer needs to know about hardware enablement is
represented in the Ubuntu archive by "OEM enablement metapackages"; that
is, packages called oem-*-meta which the installer can match (via
modaliases) to the running hardware. After release, these are SRUed into
-updates more or less as normal. The installer needs to 'apt update'
before running 'ubuntu-drivers list-oem' to learn the latest state.
[ QA ]
1. Boot the focal release live session on a newly-enabled SKU.
2. *Without updating the apt indexes*, install this SRU, i.e. download it and
use "dpkg -i".
[[ QA 1 ]]
3. Try to install normally. Get online when the wifi page prompts you to. Make
sure that the oem-<sku>-meta package is installed.
[[ QA 2 ]]
3. Do not connect to the internet. Make sure that the install completes (OEM
enablement packages will not be installed; work to do this in the session
coming soon).
[[ QA 3 ]]
3. Connect to the internet before launching the installer. Make sure that the
oem-<sku>-meta package gets installed.
[[ QA 4 ]]
This one can be done on a non-OEM device. Here we're checking that the
'apt update' didn't mess things up.
3. Uncheck 'download updates while installing Ubuntu' and ensure that
it's respected, i.e. that the installed system still offers all the SRUs
as updates.
[ Regression potential ]
This now more-or-less unconditionally runs the equivalent of 'apt
update' from the installer.
1. It'll slow down the install a bit. But shouldn't be too bad, since
only post-release pockets will have changed. If you're online before you
start ubiquity it will be less noticable since it is done in the
background. If you get online from the installer then there will be a
short delay.
2. Perhaps some part of the installer gets sad or installs the wrong
thing if you've update the apt indexes. We have a check box 'download
updates while installing ubuntu' that should still be respected.
