Hello Linux Geeksters. As you may know, CDemu is an open-source, CD-ROM/DVD-ROM emulator, used for emulating CDs and DVDs.

The client can be controlled via either a textmode and a GTK client, it requires the libmirage library to interpret optical disc images and contains a kernel module for the virtuald drive controller.
The latest version available is CDemu 3.0.0, which has been released a while ago.
In this article I will show you how to install CDemu 3.0.0 on Ubuntu 14.10 Utopic Unicorn, Ubuntu 14.04 Trusty Tahr, Linux Mint 17.1 Rebecca, Linux Mint 17 Qiana, Pinguy OS 14.04, Elementary OS 0.3 Freya, Deepin 2014, Peppermint Five, LXLE 14.04, Linux Lite 2.0 and other Ubuntu 14.10 and Ubuntu 14.04 derivative systems.
