This one, before you commented it out, only contained non-free-firmware and *not* non-free. They are two different sections. > deb http://ftp.debian.org/debian/ bookworm main non-free non-free-firmware Here, someone has added non-free. If that's not what you want, you can remove that. You should *keep* non-free-firmware, though. Also, if you don't want to use plain http, you can change this to https. > deb http://ftp.debian.org/debian/ bookworm-security main non-free > non-free-firmware This one is incorrect, but someone else already addressed that one. Be sure you actually follow their instructions correctly. The hostnames security.debian.org and ftp.security.debian.org are not the same.
