Try use the terminal as it shows better what have gone wrong. I am not sure if this is the correct path for the log.. but if you use "leafpad /home/user/.hildon-application-manager/last-update" it should show you a log. You will need leafpad installed. You did right by this.. sudo gainroot apt-get update apt-get install libsdl-ttf2.0 But try with moodlight instead.. sudo gainroot apt-get update apt-get install moodlight Or all not upgraded.. sudo gainroot apt-get update apt-get upgrade and.. apt-get autoremove If you want to install many programs at the same time.. then just add with a space between. "apt-get install moodlight leafpad libfribidio" e.t.c.
Or all not upgraded..
