   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   
      
   Error message:

   Error: The repository 'http://archive.raspberrypi.org/debian trixie InRelea

   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.
