I have quite a few Raspberry Pi doing various jobs all running Bookworm.

They are stable and I regularly update them.

Trixie is here but I see no reason to update.

So the question is how long will Bookworm be supported before I have to upgrade to get security patches etc?

If anyone publishes lifecyle information for Raspberry Pi OS then I
haven?t yet found it. Effective end of life could be any time between
?already abandoned? and matched to Debian, I don?t know.

Fortunately most of my PI projects need to work and stay working without
any upgrades, ever.
I try and pick the latest, get it working, add all the extra bits I need
and that's it.

That suggests that the current Debian Testing will be released (as
"Forky") around the middle of 2027, not 2026, and that is when Trixie
will become "oldstable". Oldstable is still supported by the Debian
team, so Bookworm should get updates until at least mid 2027 and Trixie
until at least mid 2029.

Raspberry Pi OS is based on the ARM build of standard Debian, with some Pi-specific content provided by Raspberry Pi themselves. There is a
comments by Gordon Hollingworth of Raspberry Pi here:

https://www.raspberrypi.com/news/trixie-the-new-version-of-raspberry-pi-os/

That says:

Debian Bookworm will be supported for another two years by
Debian. We will release new Linux kernels for the legacy OS
for critical vulnerabilities. But otherwise there won?t be
any updates to Raspberry Pi specific packages.

There will still be updates direct from Debian, of course.

If you look in /etc/apt/sources.list.d (in Trixie, on a Pi) you'll find
two files named debian.sources and raspi.sources; those list the online repositories that are used for updates. Most updates come direct from
Debian.

I have a box running Buster (AMD64) and that still gets updates (must
get around to updating it).

I've been spending some time debugging Bluetooth issues recently and I
would strongly advise anyone using Bluetooth devices to be careful with upgrading... there seems to be some bug somewhere in the processing chain,
and I'm guessing user-space, as opposed to the kernel.

I?m not quite sure where you?re getting some of those timelines from,
but anyway, the relevant part is the the table giving release end of
life dates, and the EOL for bookworm is June 2026.

There is an LTS process, though, which looks like it?ll extend bookworm security support into 2028, albeit that they don?t seem to have decided
on the scope for bookworm LTS yet (thought it?d be surprising if it
excluded arm64).

Right. So Debian userland and the Pi kernel are still in support but Pi-specific userland is already out of support.

What about this?

The Debian 12 life cycle encompasses five years: the initial three years
of full Debian support, until June 10th, 2026, and two years of Long
Term Support (LTS), until June 30th, 2028. The set of supported
architectures is reduced during the LTS term. For more information,
please refer to the Security Information webpage and the LTS section of
the Debian Wiki.
