I keep getting the tray notification that I have updates. But when I double click on it to get the updates it tries to reload the package list from the server.

I get this error.

But after I click Ok nothing happens. A little bit later the tray icon comes back saying I have updates. I know I can import the GPG signature to get rid of that error but it's a little tedious. They really need to streamline that process. Plus that error is a bit cryptic don't you think?
