On an NUC PC (Intel) I do get this message: The following packages have been kept back - linux-image-amd64
Never had this message before.
I am running DietPi v9.14.2
Thanks for any help
did you already tried to install the package?
apt install linux-image-amd64
And a small hint, you don’t need to do screen prints. Simply copy past your SSH terminal output.

Just tried that:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
linux-image-6.12.32+bpo-amd64 : PreDepends: linux-base (>= 4.12~) but 4.9 is to be installed
E: Unable to correct problems, you have held broken packages.

You must now follow the dependency tree and see where exactly the dependency problem lies
apt install linux-base

linux-base is already the newest version (4.9).
linux-base set to manually installed.

can you try this one
apt install --reinstall linux-base
AAHHH wait,
it seems the kernel has been installed from backports. Debian -- Details of package linux-image-amd64 in bookworm-backports
Therefore, the base package is not matching. Did you have done this by purpose?
That was based on an advice from @MichaIng due to problems with Thunderbolt
sudo apt update
sudo apt install -t bookworm-backports linux-image-amd64
Have a look here:
It depends on the linux-base package from backports as well. apt upgrade is conservative when upgrades would pull in dependencies from other suites. Try this again, telling it to use backports explicitly (including dependencies where needed):
sudo apt install -t bookworm-backports linux-image-amd64
Since linux-base is from backports afterwards, future upgrades won’t be hold back anymore.

Do you want to continue? [Y/n]
Is it OK to say “Yes”?
Yes, this is the expected summary.
