So I have ran into some trouble installing g++. When I try to use the "sudo apt install g++", command it asks me if I really want to install it, and when I say yes, it just leaves me this message: "Insert the „Ubuntu 20.04.2 LTS Focal Fossa - Release amd64 (20210204)” called CD to the /cdrom/ drive and press enter" (Or something like that, I tried to translate it from Hungarian)

I give you an image of my problem, however my Ubuntu is in Hungarian, so i don't think that it would be useful. Here it is: My terminal, under Ubuntu 20.04.02.0

I have already tried to get the .iso file and just mount it to my cd drive, but it didn't solve the problem.

Should I just reinstall Ubuntu or what should I do?

The problem looks like you must have put your sources (where Ubuntu gets the packages) to only the install CD.

Fix this by opening the Software and Updates app, and ticking everything (you want to install) listed under Downloadable from the Internet.
