Can't get subtitles to appear (Alpha 2)

Hello… I’m also new to this… When I try to make that command (sudo apt-get install libass5) in my terminal to Openelec I get the following reply.

There is no working ‘sudo’.

On debian/ubuntu/all general purpose linux distributions ‘sudo’
allows a permitted user to execute a command as the superuser
or another user, as specified by the security policy

With OpenELEC you have root access by default, so you dont need ‘sudo’

VERY informate but also very confusing… I’m guessing you guys control your media station in some other way. Care to tell me how?

Thanks in advance…
