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.
