I would like to install gcc compiler by this command apt install build-essential

and after pressing Yes, it asks me to insert some media.

Media change: please insert the disc labeled
'Ubuntu 18.04.4 LTS _Bionic Beaver_ - Release amd64 (20200203.1)' in the drive '/media/cdrom/' and press [Enter]

and this prompt repeats again and again

What's wrong?

Edit /etc/apt/sources.list and put # in front of the line with cdrom

You need to be coneected to the internet to be able to install gcc.
