Upgrade Raspberry Pi Desktop 2022 to Debian 12

Upgrade Raspberry Pi Desktop 2022 to Debian 12

Much older Rpi Desktop

The reason I want to upgrade the Raspberry Pi Desktop to Debian 12 Bookworm is just to try out the new Linux kernel 6. The older kernel 5, released in 2019, is about 3-4 years old.

The upgrade takes me around 4 hours on my (older) machine. After upgrading, a lot of the Raspberry Pi Desktop settings were changed, and seems slower at the first glance. My advice is not to upgrade until the official release is out for Raspberry Pi Desktop OS.

How to upgrade?

Change the APT source from Bullseye (version 11) to Bookworm (12). Bullseye and bookworm are the code name for the Debian OS version.

  
# edit /etc/apt/sources.list /etc/apt/sources.list.d/raspi.list
