I get this error when I attempt to install anything using the built-in addon installer for themes and things like that.

It shows up in the bottom left. Here's a picture.


I'm running Ubuntu 14.10 with KDE desktop (and applications) installed, everything else works fine. How can I fix this? Thanks.

EDIT: Sorry! Wrong forum section? It automatically made me post here.

It is not you, I get it whenever I try to use the GetHotNewStuf functionality - the server(s) hosting it are currently down
