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.

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.listor alternativelysudo nano /etc/apt/sources.listin a terminal.In the editor save by using the key combo
Ctrl+Sand exit withCtrl+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 mainRight, 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-kdein (K)ubuntu)?To add to what @lordnikon said, the program is called Software & Updates and I’m pretty sure it’s installed by default in GNOME (don’t know about other DEs).
Cheers! Yes it’s the same as in KDE. The command-line call is
software-properties-gtkorsoftware-properties-kde.
yes it can be changed just to un check the box that says Cdrom in sources list. you may need to install that package as im not sure it is installed on debian by default. I start with a minimum install and build my system from there so it’s been a long time since I have seen a default install.
Cheers! Good to know for when I also switch to Debian :)
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.
