Installing Kodi Ubuntu 14.04

Refer: http://ubuntuhandbook.org/index.php/2016/02/kodi-16-released-how-to-install-it-via-ppa/

$ sudo add-apt-repository ppa:team-xbmc/ppa
$ sudo apt-get update
$ sudo apt-get install kodi

This probably won't be needed
sudo apt-get install --install-suggests kodi

Helpful Hint
Kodi the \ is the shortcut key to toggle between fullscreen and window

Refer: http://askubuntu.com/questions/849396/uninstall-kodi-on-ubuntu-14

If you need to remove and purge an application and finally removing/purging also the application configurations files, do so by using the following commands:

$ sudo apt-get update
$ sudo apt-get remove kodi*
$ sudo apt-get purge kodi*

Then remove the settings folder to remove all settings and library data. This will not delete any videos or music, but just the settings and library data itself:

$ rm -r ~/.kodi/
or
$ rm -r ~/.xbmc/
for older versions before 14.0

Type about:config into the URL bar, and confirm you'll be careful by clicking the I'll be careful, I promise button. 2. Search for the string labeled media.autoplay and double-click it to flip its status to off. Opera and Chrome have an extension that prevents videos from playing automatically.
