RPi3B - Upgraded from dietpi 8.5 to 9.2.1, stuck on kernel 5.10?

Hello all,
I have a Pi3B currently running DietPi 9.2.1, that I recently upgraded from 8.5. In addition to running dietpi-upgrade, I ran the script provided in section 3.2 of this blog post to upgrade from Bullseye to Bookworm, which completed successfully. I have run apt update and rebooted multiple times, but no new kernels are listed as available. apt-mark showhold doesn’t list any packages being held back, so I’m not sure what’s going on.

My current kernel version is 5.10.103-v7+. I have never built or installed a different kernel than what is supplied by default on this machine.

I need a newer kernel in order to use an RV-3032 i2c RTC, support for which was added in 5.15.73. https://github.com/raspberrypi/firmware/commit/1e2374e9de5a16ef7f1a3ea2267dd6abafb6c4e8

Any help or guidance would be greatly appreciated. Thanks!

Check you sources.list

cat /etc/apt/sources.list

(there script should have cared about that, but maybe something went wrong?)

You can also try to run sudo apt full-upgrade or sudo apt dist-upgrade.

If this does not help you could manually install the kernel image.

sources.list contains:
deb http://raspbian.raspberrypi.com/raspbian/ bookworm main contrib non-free

sources.list.d/raspi.list contains:
deb https://archive.raspberrypi.com/debian/ bookworm main

There are no other sources present. apt full-upgrade found a bunch of old packages to remove, but no new kernels. dist-upgrade also finds nothing new.

Do you use anything like Berryboot? Do you boot from SD card or USB device?

A post was split to a new topic: RPI kernel update to 6.6

Not familiar with Berryboot - my install is fairly “stock”. Boot from a USB device.

Do you have just the USB device connected or a SD card in addition.

Never found a solution, it’s still stuck at the old kernel.

@millerjs the issue of @Ramirri is completely different. Don’t mix them. Both are not related.
