I can't install any new software, i keep getting this message

Question

'Ubuntu 18.04 LTS _Bionic Beaver_ - Release amd64 (20180426)' in the drive
   '/media/cdrom/' and press [Enter]

When I press Enter, nothing happens. I tried updating and upgrading my packages so that’s not the issue.

I’m new at Ubuntu so I don’t know what else to do.

@DavidFoerster why you like to scroll this message? It is unreadable and ugly that way (">"). — N0rbert, Jul 15 '18 at 11:57
@DavidFoerster You are absolutely right about formatting, but on my Firefox ESR it is scrollable (see image). — N0rbert, Jul 15 '18 at 12:05
@N0rbert: My mistake. I forgot the user style sheet that forces the style white-space: pre-wrap onto all <pre> nodes (precisely because I don't like to scroll horizontally). — David Foerster, Jul 15 '18 at 12:11
@PerlDuck SeaMonkey and Chromium too. Of course I mistaken - instead of > I mean four spaces. Opened thread on Meta. — N0rbert, Jul 15 '18 at 12:27

You should:

open Software & Updates (or software-properties-gtk from terminal)
then in the area named Installable from CD-ROM/DVD uncheck the Cdrom with Ubuntu 18.04 (Bionic Beaver).
make sure that you do not have checked Cdrom with Ubuntu 18.04 'Bionic Beaver' on Other Software tab:
to keep your system secure on Updates tab enable security updates (bionic-security, bionic-updates, bionic-backports):

Usually it was a CD/DVD medium from where the system were installed first time. – N0rbert Apr 30 '19 at 20:05
