Openstack using DevStack - Failed to fetch cdrom

Hi,

While going over all the configuration needed with devstack for open stack and during the installation - after running ./stack.sh i received an error
"failed to fetch cdrom ...."

To solve this, go into /etc/apt
do 'sudo nano sources.list' and remove by using '#" the cd rom line.

Then start again the ./stack.sh and it will work

you just removed / disabled the cd rom
