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?
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 alternativelysudo nano /etc/apt/sources.list
in a terminal.In the editor save by using the key combo
Ctrl+S
and 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 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)?
