Trying to install VirtualBox on 12.04 and I get a message saying to insert the following CD to continue:

Ubuntu 12.04 LTS Precise Pangolin - Release amd64 (20120425)

Does anyone know where I can get this CD or its contents?

At what stage of the installation? What have you done so far? – Oli Aug 23 '12 at 15:55
I am just trying to download it from software centre – Josh Aug 23 '12 at 15:57

Your version of Ubuntu was originally installed from that CD/DVD. If you still have it, put in in the drive.

Alternatively, you will need to edit the file /etc/apt/sources.list and comment out (add a '#' character at the start) the line starting deb cdrom:....

I do this using a terminal session. There may be a GUI to do this but I've never looked for one.

There is indeed a GUI ; from Software Centre, go to Edit .. Software Sources, go to the "Other" tab, and uncheck the relevant entry. – Adrian Aug 23 '12 at 19:15
Oh I didn't realises it was that CD, I do still have it... Somewhere, Thanks :) – Josh Aug 23 '12 at 21:05

Try installing virtualbox from the command line:

sudo apt-get install virtualbox

OR download the deb packages, if you're using Ubuntu 12.04, using the following links:

For i386:

For x64:

If you're using some other version of Ubuntu, download virtualbox from here.

Go to the folder where the file was downloaded and run:

sudo dpkg -i virtualbox-4.1_4.1.20-80170~Ubuntu~precise_amd64.deb

Change the file name according to the version downloaded.
