open terminal in folder or cd into directory of firmware tar
sudo dpkg -i *.deb

Third-party Media Codecs & Extras
By default, Ubuntu does not provide any media codec to play multimedia files. So to enjoy movies, music, and entertaining application, you need to install media codecs. Use the following code into Terminal.
sudo apt install ubuntu-restricted-extras
Here I recommend installing the free version of libavcodec also to avoid an issue while performing media task with video editors or transcoder. Use the following code.
sudo apt install libavcodec-extra
Moreover, to enable encrypted DVD playback, you have to install… “libdvd-pkg.”
sudo apt install libdvd-pkg
