basically, I'm a super noob to Kubuntu, and when I go to update using Sudo apt-get update. I get the following code:
~$ sudo apt-get update
Ign:1 cdrom://Kubuntu 20.04.1 LTS _Focal Fossa_ - Release amd64 (20200731) focal InRelease
Err:2 cdrom://Kubuntu 20.04.1 LTS _Focal Fossa_ - Release amd64 (20200731) focal Release
Please use apt-cdrom to make this CD-ROM recognized by APT. apt-get update cannot be used t
o add new CD-ROMs
Hit:3 http://archive.canonical.com/ubuntu focal InRelease
Hit:4 http://archive.ubuntu.com/ubuntu focal InRelease
Get:5 http://archive.ubuntu.com/ubuntu focal-updates InRelease [114 kB]
Hit:6 http://archive.ubuntu.com/ubuntu focal-backports InRelease
Get:7 http://archive.ubuntu.com/ubuntu focal-security InRelease [109 kB]
Reading package lists... Done
E: The repository 'cdrom://Kubuntu 20.04.1 LTS _Focal Fossa_ - Release amd64 (20200731) focal
Release' does not have a Release file.
N: Updating from such a repository can't be done securely and is therefore disabled by defau
lt.
N: See apt-secure(8) manpage for repository creation and user configuration details.
Any help would be greatly appreciated!!
