I have tried several programs such as Brassero to copy an encrypted DVD but without success. I tried to install libdvdcss but was unable to do it (key not found?).
What version of libdvdcss do I need for Ubuntu 16.04 and how do I install it? Or is there something else I need to do?

Ask the system:

Ignoring your "unable to do it (key not found?)" message due to lack of specific information.
1This is unlikely to be the answer that you want as your question doesn't indicate exactly what you are trying to do, however, you can obtain an exact copy of any block device by utilizing the method outlined here. Since you are creating an image of the device contents without regard to what those contents are, the encryption will be duplicated along with everything else. During the process of attempting to image the disk you may discover that the problem isn't the encryption, but scratches or smudges or a device problem instead. This will be made clearer by the I/O errors that dd will provide in the attempt.
