From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Did I mess up by doing that and create a situation like that?
No, this is standard procedure. Your system and software have been updated to the latest, stable version. Unless you actively add a repo containing unstable software versions, there shouldn't be anything to worry about.
Perfect I just wanted to make sure I was worried it may have automatically added them without the CD ROM one holding it in place or something like that. Thank you so much!
You really only need the "CD ROM" repo for the base install from physical media; maybe there are edge cases where you'd want to roll back, but on the whole you're in safe hands with the official, Debian stable repos 🙂
Enjoy the Linux journey! Debian is a great starting point to learn from, IMHO.
If you use netinstall you won't have any CD-ROM sources in sources.list. I think that's kind of stupid that the full iso installer even adds the CD-ROM line. The vast majority of people wouldn't want that and it just confuses new users.
Hey! Congrats on getting everything installed and situated so far.
Thank you so much! Its been a lot of fun learning and all of you on here have made it a super enjoyable experience.
Really. For a new user, fixing the repos is one of the less intuitive things to do.
On debian i just comment out all except the main official repos that I want. As long as you have the main deb and security and updates ones i think you'll be fine.
I tend to go for flatpak or appimage for anything not in those. I'd avoid any testing, unstable , backport sources unless you know what you're getting into.
I guess you're maybe using aptitude to avoid cli, but i'd recommend at least looking at the /etc/apt/soures.list file, and any stuff in the subfolder /etc/apt/soures.list.d
This is the list of where it looks for software. If it can't connect to any of those, It'll probably warn you about an unavailable source.
