Hello Thomas,

I suppose you installed stardict from ubuntu repositories.
Did you see suggestions for installing additional dictionaries in

You may find useful to get some references about sudo and gksu (kdesu
for Kde) and their usage.
Two of them [2] and [3] are linked below and you can always see what
commands man sudo and man gksu or man kdesu reveal for you.

In the link [1] are exact instructions how to do that.
