dkms (2.8.7-2ubuntu2.1) jammy depends on gcc-12 which is under universe archive

[Description]

The latest dkms(2.8.7-2ubuntu2.1) depends on gcc-12 which is in universe archive.

https://packages.ubuntu.com/search?keywords=gcc-12
gcc-12 is under main for kinect, and the patches are cherry-picked from kinect/stable, I suppose it is a mistake for jammy in universe.

dkms (2.8.7-2ubuntu2.1) jammy; urgency=medium

Cherry-pick patches from kinetic/stable to address building dkms
modules correctly for HWE kernels (LP: #1991664):

Fix dkms-autopkgtest when a given dkms package is built into the
kernel already of the same version. (i.e. zfs-linux on Ubuntu).

Use exact compiler for dkms as used to build the kernel, when
possible.

Depend on gcc-12 to build modules for HWE kernels correctly.

Hi Matthias,

 gcc-12 looks in a wrong archive, could you help fix it? Or do you know who could fix it? Thanks!

Status changed to 'Confirmed' because the bug affects multiple users.

[Steve Langasek (vorlon)]

Because gcc-12 source is in main already, *and* is already published in jammy-{security,updates}, it seems it is straightforward to simply promote the binaries to solve this problem.

I'll work on this; it may take a couple of rounds to get all the dependencies promoted.

[Steve Langasek (vorlon)]

Promoting gcc-12 and cpp-12 binaries was sufficient to fix this.

since gcc-12 is now in main, this does not affect the OEM project any longer.
