Installation • Re: “Warning: Target” “configured multiple times” in sources lists

Thank you for your replies! I found how to get the contents of the two sources lists, so here are the readouts :
$ cat /etc/apt/sources.list :

#deb cdrom:[Debian GNU/Linux 13.1.0 _Trixie_ - Official amd64 DVD Binary-1 with firmware 20250906-10:24]/ trixie contrib main non-free-firmware

deb http://deb.debian.org/debian/ trixie main non-free-firmware
deb-src http://deb.debian.org/debian/ trixie main non-free-firmware

deb http://security.debian.org/debian-security trixie-security main non-free-firmware
deb-src http://security.debian.org/debian-security trixie-security main non-free-firmware

# trixie-updates, to get updates before a point release is made;
# see https://www.debian.org/doc/manuals/debi ... _backports
deb http://deb.debian.org/debian/ trixie-updates main non-free-firmware
deb-src http://deb.debian.org/debian/ trixie-updates main non-free-firmware

# This system was installed using removable media other than
# CD/DVD/BD (e.g. USB stick, SD card, ISO image file).
# The matching "deb cdrom" entries were disabled at the end
# of the installation process.
# For information about how to configure apt package sources,
# see the sources.list(5) manual.

And ; $ cat /etc/apt/sources.list.d/debian.sources

(About the point size: I was trying to give an idea of how many of those "Warning" messages there were, when copied to a document. I should simply have figured the number; there are 108 warning messages.)
