Every time I try to download something; both via terminal or GUI app, it says "Media change :please insert the disc labeled 'Debian GNU/Linux 12.1.0_Bookworm_ - Official amd64 DVD Binary-1 with firmware 20230722-10:49' in the drive '/media/cdrom/' and press [Enter]"


1 Answer 1


Remove the cdrom entries in /etc/apt/sources.list

Here is the default config for bookworm (Debian 12):

deb http://deb.debian.org/debian bookworm main
deb http://deb.debian.org/debian bookworm-updates main
deb http://deb.debian.org/debian-security bookworm-security main

If this does not solve the problem, please give us your sources.list so we may help you.
