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
non-free rpi

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.
