The cdemu packages from deb multimedia repo is broken, so we will have to use ubuntu PPA for this.
Add ubuntu PPA Ref link
sudo nano /etc/apt/sources.list.d/cdemu.list
with content:
# cdemu source
deb http://ppa.launchpad.net/cdemu/ppa/ubuntu/ bionic main
deb-src http://ppa.launchpad.net/cdemu/ppa/ubuntu/ bionic main
