How should I install libdvdcss.so.2 (Library) to Ubuntu 16.04

I'd like to make a Copy of a DVD using Brasero Disc Burner.

It says I can't do it because I haven't got libdvdcss.so.2 (Library), which I should install manually.

I tried

sudo apt-get install libdvdread4

and then

sudo /usr/share/doc/libdvdread4/install-css.sh

but the immediate output is

sudo: /usr/share/doc/libdvdread4/install-css.sh: command not found

How should I install libdvdcss.so.2 manually?

In Ubuntu 16.04 they changed a way to install libdvdcss2.

Install it by

sudo apt install libdvd-pkg

and follow on-screen directions.
