... you can't download anything from the maemo repositories at the moment as their server is down till Monday ... http://talk.maemo.org/showthread.php?t=41023

... you should however still be able to download from the Ovi Store ... you don't do that through the App Manager though ... click the Ovi Store icon from the main menu, and it should take you to their webpage where you should still be able to download things ...

ETA ... the right link!
