Software Updates has different packages from apt/synaptic, wants to install different kernel

[Ben Romer]

I am running Ubuntu 23.04 Lunar. This morning I booted up my laptop and received notification in Software Updates that I needed to install the Oracle 6.2-1008 kernel and related modules from the NVidia driver. I closed it and ran 'apt dist-upgrade' instead and received a different list of upgrades:

$ sudo apt dist-upgrade

The following packages have been kept back:
  libnvidia-cfg1-530 libnvidia-cfg1-535 libnvidia-common-530
  libnvidia-common-535 libnvidia-compute-530 libnvidia-compute-530:i386

The following packages will be upgraded:
  linux-firmware signal-desktop
2 upgraded, 0 newly installed, 0 to remove and 36 not upgraded.

I double-checked the situation with Synaptic and found that the GUI there agreed with the APT output and did not want to install the Oracle kernel. Screenshots attached.

Expected behavior: the three programs should have the same list of upgrades available.

Synaptic has the same behavior as Software Updates if you click "Mark all upgrades".
