I've been trying to get Ubuntu GNOME 17.04 and finally got it to boot, however it failed near the end of the installation leaving my apt repositories not set up correctly. Hopefully this is the only part that failed, however I am just taking this one step at a time. This is what it says when I try to update:

CorruptComputer@Ubuntu-GNOME:~$ sudo apt update

N: Updating from such a repository can't be done securely, and is therefore disabled by default.

  • The only error is about cd-rom, about the media you used to install. You can (and should) remove or disable it safely. Settings > Software & Updates > Other software. –  Apr 17 '17 at 04:59

I was able to fix this by following the same steps in the answer here: How do I restore the default repositories?
