raspberry pi trixie sources list

Dec 15, 2025 Last reply: 7 months ago 8 Replies

I've just upgraded my pi4 from Bookworm to Trixie, although it's not recommended. Fortunately, everything is ok except a problem of apt. It seems the sources.list is not correct as I got an error message when I run command apt update, if I switch on the source

trixie main



I'm not sure if Trixie doesn't have this source or the source is not correct?


If you've made a mistake in this file, you haven't actually upgraded anything yet.

Thanks for your reply. I got the error message after I upgraded my system.

Current version is as below:

attend@rpi4:~$ hostnamectl Static hostname: rpi4 Icon name: computer Machine ID: c6055edb7388468797fd905b62e0b32b Boot ID: 190ad998508f4bc2bfe264480a61a92c Operating System: Raspbian GNU/Linux 13 (trixie) Kernel: Linux 6.1.21-v8+ Architecture: arm64

Nobody here is telepathic, so you’re going to have to say what the error message is.

Thanks for your reply. I was thinking it could be a problem in my sources.list, but it's useful to show the error messages and my sources.list as you said.

I replaced bookworm to trixie in file sources.list when I upgraded my system. The error message came out after upgrade completed.

The most possible reason could be the signature need to be updated for the source

trixie InRelease , but I jsut want to check if it is correct first.

Bookworm is still good until June 30th, 2028, is it not?

If you are not on the internet nor likely to load any further code on it, its good forever...

What do the following output?

dpkg --audit

dpkg -l libc6 raspberrypi-archive-keyring

Thanks for your reply. I just downloaded a fresh installation pack from

And copied the files in folders /etc/apt/sources.list.d and /usr/share/keyrings$ of this package to my pi4. Then there is no error message when I update my system. Hopefully I can receive updates again in the next few days.

Comparing to previous version, pgp files are updated and the website changed from org to com.

Current pgp files in /usr/share/keyrings folder are as listed below:

raspberrypi-archive-keyring.pgp raspberrypi-archive-automatic.pgp raspbian-archive-keyring.gpg

In the sources.list.d folder files are as below:
