Download the deb etc. I have no idea what these things are. If you click System -> Admin -> software sources and manually choose (don't click "use best server") a server, does it suppress the failed to fetch errors?

If you're using Indonesian mobile operator, make sure tell your operator to disable adpop.

Can you help with this problem?
