Comment 6 for bug 875423

Yes, /etc/apt/sources.list says at the top:
# deb cdrom:[Ubuntu 9.10 _Karmic Koala_ - Release amd64 (20091027)]/ karmic main restricted

How is this not a bug? Requiring removal of a comment in this file to fix this dialog doing nothing at all when clicking "ask me later"? At the very least it seems the dialog should pop up a message saying "sorry, I can't do anything until you remove this line from your /etc/apt/sources.list". But it still seems ridiculous to have that requirement. Why is this comment line even a problem?

I'm plenty capable of doing the upgrade without this dialog, I just think the dialog is doing a very wrong thing (nothing), pretty far from the user friendliness I've come to expect form Ubuntu.
