How to Upgrade Raspberry Pi OS from Bullseye to Bookworm
This guide highlights the risky process of upgrading from Raspberry Pi OS Bullseye to Bookworm, emphasizing the complexity introduced by significant changes in Bookworm. While an upgrade from Bullseye is possible, the guide acknowledges potential issues and recommends considering a fresh installation of Bookworm to avoid missing crucial changes. Notably, Raspberry Pi OS Bookworm introduces notable alterations, such as the shift to Network Manager for networking and the transition from X11 to Wayland.
The guide provides a step-by-step procedure for upgrading from Bullseye to Bookworm. It stresses the importance of installing Network Manager before the upgrade to ensure smooth networking functionality. The process involves updating the operating system, changing official repositories to point to Bookworm, and upgrading packages. Specific commands are provided to modify repository files, and users are cautioned to proceed with care due to changes in kernel package names. The upgrade also involves adjustments to the file system and boot partition, highlighting the intricate nature of the transition.
The final steps of the upgrade guide focus on upgrading the kernel and firmware to align with Bookworm. The guide includes commands tailored for different Raspberry Pi models and operating system configurations. It covers tasks such as purging existing Bullseye bootloader and kernel, creating new directories, and adjusting the system manager’s configuration. Additionally, users are directed to reinstall firmware and kernel packages according to their specific Raspberry Pi model and operating system version. The guide concludes with the essential task of adding the “auto_initramfs” option to the config file, ensuring compatibility with the new initramfs file included in the move from Bullseye to Bookworm. Finally, users are prompted to restart their Raspberry Pi, completing the migration process.
