I am unable to play a DVD

VERSION="20.04.3 LTS (Focal Fossa)" Dell Latitude

I can see files on the CD Drive

When I click videos the player opens and I see this error..

Unable to play the file DVD source is required to play the file, but is not installed.

Find in Ubuntu Software fails when I click on the button.

Solution 1:

Retail DVDs are usually encrypted and you need software to decrypt the DVD in order to play them.

To install the necessary library, open a terminal and run:

sudo apt update

Then run:

sudo apt install libdvd-pkg && sudo dpkg-reconfigure libdvd-pkg

With this library installed, you should be able to play encoded DVDs with media players like VLC and MPlayer.
