HOWTO: Upgrade Raspberry Pi OS from Bullseye to Bookworm

I don't see the file /usr/lib/systemd/system/NetworkManager.service.d/10-dhcpcd.conf on a raspiOS lite 32 bit. What is your OS?

I have it on a Raspbian Bookworm 32-bit

I just looked at the following images:

  • 2024-03-15-raspios-bookworm-arm64.img.xz
  • 2024-03-15-raspios-bookworm-arm64-lite.img.xz
  • 2024-03-15-raspios-bookworm-armhf.img.xz

available at https://www.raspberrypi.com/software/operating-systems/

And the file is not present in the image themselves. So It must have been added after the first boot or some other way...

May be the instruction must include instead the deletion of that said failed ie.:

rm /usr/lib/systemd/system/NetworkManager.service.d/10-dhcpcd.conf
???

/lib/systemd/system/NetworkManager.service.d/10-dhcpcd.conf is part of dhcpcd5 1:8.1.2-1+rpt9

This is about upgrading. If dhcpcd5 was part of your "old" OS version, it will be upgraded and available ... . It is not part of a new Bookworm install.

And no, I would not delete this file. You might apt-get remove dhcpcd5, this should work (untested).

sudo sed -i.bak '$ a\auto_initramfs=1' /boot/firmware/config.txt

broke it for me. Raspi didn't boot with auto_initramfs set to 1 anymore. Reverted it to 0 and boot with new kernel was successful.

# Switch to NetworkManager from dhcpcd
sudo systemctl enable --now NetworkManager
sudo systemctl disable --now dhcpcd

Noteable here is that NetworkManager ignores all interfaces defined in /etc/network/interfaces*. The interfaces must be removed from there to get visible in NetworkManager.

Edit: I'm on a Raspberry Pi 2 Model B

Raspberry PI 4 Model B, 64bit, installed in NVMe disk. Just upgraded to bookworm with kernel, without problems :)

@hartacus
Copy link

I've (mostly) followed these steps and now have Bookworm running on my Raspberry Pi model B. Notes:

  • Lines 18-25 (contents of sources.list) only apply to 64-bit installations, not 32-bit installations. Lines 14-16 take care of sources.list based on your current install's bitness so just trust those.
  • I was using an SD card from a fresh bookworm install (backed out of that, too much work) with root on an external SSD that still had bullseye installed. This booted fine with the SD card mounted at /boot, but IPv6 didn't work (I run dual stack). After making a backup copy of /boot, I followed lines 41-59, though I purged raspberrypi-kernel and raspberrypi-bootloader after unmounting /boot instead of before. New kernel (6.6.47+rpt-rpi-v6) installed fine and IPv6 was enabled after reboot.
  • The above issues with IPv6 caused the initial upgrade to fail because my nginx config files had IPv6 addresses. I had to comment those out of the nginx config files then manually install nginx-full which allowed the upgrade to complete successfully.
  • I already had auto_initramfs=1 in my config.txt

For people who have issues with switching the kernel packages. If you have this kind of error:

E: Sub-process /usr/bin/dpkg returned an error code (1)
linux-update-symlinks failed to create symbolic link

(I don't remember the exact error message)

  1. make sure that you have mounted the firmware partition already as /boot/firmware instead of /boot and that the fstab is correct
  2. create the file /etc/kernel-img.conf with the content:
do_symlinks = yes
no_symlinks = no
image_dest = /boot
link_in_boot = true
  1. run sudo apt --fix-broken install
