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

http://archive.raspberrypi.org/debian 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.

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

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

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.

Sources.list:

deb http://raspbian.raspberrypi.org/raspbian/ trixie main contrib
non-free rpi
deb http://archive.raspberrypi.org/debian/ trixie main
# Uncomment line below then 'apt-get update' to enable 'apt-get source' #deb-src http://raspbian.raspberrypi.org/raspbian/ trixie main contrib

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 http://archive.raspberrypi.org/debian trixie InRelease , but
I jsut want to check if it is correct first.

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
