Ubuntu – Does it always say “Requires Installation of Untrusted Packages” and not let me download


As the Title above asks, Why can't I install any packages? I tried installing emesene (Other applications wont install either, just using emesene as an example) but It wont download due to "Untrusted Packages" and gives me "emesene python-libmimic" when I click Details.

What's wrong? Before this I have installed things like KTorrent, VLC Media Player, Audacity and the like but since then nothing works.

Dont worry. Figured out the problem. I looked at my software sources again and noticed that the required sources were not ticked. Which raises the question, how were they unticked if I never touched them until now?
