Existing guides specify to install the libdvdread4 package and then run sudo /usr/share/doc/libdvdread4/install-css.sh to install DVD decryption support. However on Loki, this results in sudo: command not found. Inspecting the libdvdread4 indeed reveals that the install-css.sh script is missing.

Since Ubuntu 15.10, libdvdcss (the package required for CSS decryption) is installed as part of the libdvd-pkg package, with no additional steps required.

sudo apt install libdvd-pkg

The default Videos app in elementary OS is quite buggy, and while the Play Disc option appears after installing CSS support, playback fails. A workaround is simply to install VLC, which is generally more stable and has better format support.

sudo apt install vlc

Source and more info.

  • Aferwards I needed to sudo dpkg-reconfigure libdvd-pkg to download, compile, and install libdvdcss

On ElementaryOS 5.1 (Hera) all I needed to do (as with many other newer Ubuntu-based distros) to play DVD-s was:

Pre-requisites (which are probably already done):

sudo add-apt-repository multiverse
sudo apt update

Required setup:

sudo apt install -y gstreamer1.0-plugins-ugly gstreamer1.0-plugins-bad


  • Insert the DVD.
  • Open the Files app.
  • Click your DVD to load it on the left-hand list of Devices.
  • Open the Videos app.
  • Click the Play from Disc button in the middle.
