Debian changed the method of setting the apt sources between Bookworm and Trixie, they went from ending in '.list' to ending in '.sources'. They both contain the same basic info, but in different ways.
If you have any files in /etc/apt that end in '.sources', I suggest you open them in your favourite editor (using sudo) and comment out all lines them (place a '#' at the start of each line).
Now open /etc/apt/sources.list and make it look like this:
Close and save the file
open /etc/apt/sources.list.d/raspi.list and make it look like this:
Close and save the file.
Run 'apt update' and everthing should be back to normal.
