Re: Why has new bookwork installation given me a newer kernel than an upgraded bookworm?

That simply lists every possible matching package as far as I can see,
not what's actually installed.

The 'newer' system says /boot/kernel8.img comes from the

Don't you have to use apt-get dist-upgrade to install newer kernels?
I assumed that was to avoid the need to reboot on automated updates.

Yeah. I think I am right. The policy is not to change the kernel on
normal upgrades

I tried that, no change, still 6.1 kernel:-

Odd. apt and apt-get may have different rules
 
"apt-get upgrade only upgrades the apps, tools, and utilities. It does
not install new Linux kernel of the OS.
 
"apt upgrade upgrades the apps, tools, and utilities and installs new
Linux kernel of the OS. However, it never removes old packages.
 
"apt full-upgrade upgrades the apps, tools, and utilities and installs
new Linux kernel of the OS. It also removes old packages if needed for
the upgrade."
 
It looks to me apt full-upgrade does the same thing as apt-get
dist-upgrade. That is to say the full-upgrade will check for and install
a new kernel if available and removes old packages if the removal is
necessary for the upgrade."
 
I don't think apt dist-upgrade is actually a valid command.
 
"apt full-upgrade and apt-get dist-upgrade are the same command. But
again apt is the newer command."
 
Anyway see if any of that works., I am pretty sure it did for me

They both look the same to me, neither of them gets the latest kernel.

I think running 'rpi-update' may update the kernel but it shouldn't be necessary to do that.
