All upgradable package now is kept back even with apt full-upgrade. But I cannot find any conflict. aptitude cannot resolve the conflict either but it does not give out reason.

After run with debug flags, it seems the nvidia-dkms-525 is not installed. But why cannot the apt just install the dependencies? I added --with-new-pkgs, but it still kept back.
apt -o Debug::pkgProblemResolver=yes --with-new-pkgs upgrade

Interesting sudo apt reinstall nvidia-driver-525 works. it removed an old kernel linux-modules-nvidia-525-6.0.0-1009-oem. But that is automatically installed anyway. the full-upgrade show be able to remove it when there is conflict. Can anyone tell me how to avoid this kind of trouble in the first place?
Now there are 2 packages still cannot be upgrade:
apt -o Debug::pkgProblemResolver=yes full-upgrade

The following packages have been kept back:

0 upgraded, 0 newly installed, 0 to remove and 2 not upgraded.
But why? there is no conflict at all.
