New to linux... I have no idea how to fix this error...

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.
  
  Question: can this be done via a graphical interface (eg like software-properties-kde in (K)ubuntu)?
- Oh my lord thank you! I heard alot about the sources.list, I just had no clue what it was or where it was.
The sources.list contains a list of the sources that can be used for the installation and update of software packages. If you installed your Debian Linux distribution from a CD/DVD at some point, or maybe just by default if there is a CD/DVD player in your PC, an entry will have been added to the sources.list file corresponding to the mount point of the installation CD/DVD. Usually you can deactivate this entry after the initial installation, as I suppose that you further installs and updates will be from network sources. The full path to the location of the file is /etc/apt/sources.list. You can edit the file in a text editor, but as a newbie it is probably easier and safer to do that via your graphical update/package manager. Have fun discovering Linux.

For more information, have a look at: https://wiki.debian.org/SourcesList
I believe you just want to comment out the cdrom entry in the sources.list file.
