When I check my Update Manager it says "the package information was last updated 92 days ago". How can I update the package information without doing an upgrade or changing any of the rest of my system? I'm running 8.04 and only have a couple of complaints (like having to click Rhythmbox 2-3 times to get it to open, Just a trifle irritation), otherwise it runs smoothly. I would like to upgrade Rhythmbox (I have 0.11.5), but that seems to be all I can get for 8.04. Maybe if I could update the package information a later version might be available???
