Bug description:
[ Impact ]
When the a factory image is installed onto a new system it ends up
with very old packages installed as available when that image was
frozen. Due to the presence of strict version clamps in some older
linux-restricted-modules packages these will not upgrade as removals
are required, however the associated kernel can still upgrade. This
leads unattended-upgrades to upgrade one without the other rendering
the latest kernel unable to drive the display. A very poor user
experience on second boot.
[ Test Plan ]
Install a factory image into a VM and allow unattended-upgrades to
upgrade the system; expect the kernel to upgrade and Nvidia components
to be held-back. Then install this package and expect both to
upgrade.
[ Where problems could occur ]
The new source provides updated packages for very old and now
abandoned ABI specific packages. No current install should have the
packages we are changing nor should they be installed by normal
updates. Affected installs from frozen media should install a single
package out of this set based on their frozen ABI version releasing
the strict version clamp, and then immediately upgrade to the latest
packages in the archive. We do not expect these packages to remain
installed on any system.
[ Other Info ]
All included packages are pulled directly from the Launchpad
Librarian.

If the GMed image used earlier kernel than 5.17.0-1020-oem, then you
would like meet this issue.
1020-oem is in security channel. In jammy the unattended-upgrade will
install security fixes by default.
For the I+N platforms, the nvidia driver couldn't be installed for
1020-oem kernel, then user will meet a black screen cause of nvidia
modules couldn't be loaded.
Unattended-Upgrade::Allowed-Origins {
"${distro_id}:${distro_codename}";
"${distro_id}:${distro_codename}-security";
// Extended Security Maintenance; doesn't necessarily exist for
// every release and this system may not have it installed, but if
// available, the policy for updates is such that unattended-upgrades
// should also install from here by default.
"${distro_id}ESMApps:${distro_codename}-apps-security";
"${distro_id}ESM:${distro_codename}-infra-security";
