From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I'm on Debian 12, KDE Plasma, I often get this error

E: The repository 'cdrom://[Debian GNU/Linux 12.0.0 Bookworm - Official amd64 DVD Binary-1 with firmware 20230610-10:23] bookworm Release' does not have a Release file. W: Updating from such a repository can't be done securely, and is therefore disabled by default. W: See apt-secure(8) manpage for repository creation and user configuration details. E: cdrom://[Debian GNU/Linux 12.0.0 Bookworm - Official amd64 DVD Binary-1 with firmware 20230610-10:23] bookworm Release is not (yet) available (Please use apt-cdrom to make this CD-ROM recognized by APT. apt-get update cannot be used to add new CD-ROMs) W: http://dl.google.com/linux/earth/deb/dists/stable/InRelease: Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details.

I didn't install from a CD Rom or DVD, what is the problem here?

Okay, so I haven't installed Debian in quite some time, but I think I know what's happening here.

It's looking for the CD / DVD "repos" because it may be enabled in your apt sources. You just have to comment out the lines involved with CD and DVD in your /etc/apt/sources.list file I think.

Uh, yeah. Cheers

Since OP is new to linux I'll just add this in case it's helpful.

To edit a file owned by root (super account) you can use sudoedit /etc/apt/sources.list or alternatively sudo nano /etc/apt/sources.list in a terminal.

In the editor save by using the key combo Ctrl+S and exit with Ctrl+X.

Commenting is adding a # in front of the line.

so the file should look like something like this

# deb cdrom:[Debian GNU/Linux 11.5.0 _Bullseye_ - Official amd64 NETINST 20220910-10:38]/ bullseye main

Right, thank you. I haven't had my coffee yet. I should have been more clear.
