Thanks for your reply.  I just downloaded a fresh installation pack
from https://www.raspberrypi.com/software/operating-systems/

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:

File raspbian.sources:
Types: deb
URIs: http://raspbian.raspberrypi.com/raspbian/
Architectures: armhf
Suites: trixie
Components: main contrib non-free rpi
Signed-By: /usr/share/keyrings/raspbian-archive-keyring.gpg

File raspi.sources:
Types: deb
URIs: http://archive.raspberrypi.com/debian/
