When I tried to update using apt-get upgrade I got the following:

[sudo] password for david:

I have put the content from your "answer" into your question. Can you see the little grey bits of text underneath your question at the left hand side? One of them should say share and another should say edit. Click on edit to add content to your question. — wizzwizz4, Jan 9, 2016 at 19:44
However, don't use edit to change what you are asking in your question, or people will get cross and stop helping you. Rather, ask a new question if you have a new question! — wizzwizz4, Jan 9, 2016 at 19:45
There seem to be multiple issues here: 1) The bogus cdrom:// entries and 2) the Problem with MergeList thing. — David Foerster, Jan 11, 2016 at 2:32

I would say this looks ok. The missing CD-based package sources are simply ignored. The corresponding packages are also available from online sources.

Note that apt-get update only updates the local package index, i.e., it makes metadata about packages available locally. It doesn’t update your system.

To update your system, you should run the following in addition:

sudo apt-get upgrade

Open a terminal
Type in sudo nano /etc/apt/sources.list
Remove the lines containing the word cdrom
Exit with Ctrl+X, Y and finally Enter
Update the package list with sudo apt-get update
