I am regularly being notified that updates are available via a green puzzle piece thing in the bottom right corner that pops up as well as a green circle with white arrow in the top right corner that is always there.

Whenever I try to get updates by clicking on one of these I get a pop up box that procedes to check for updates. The status bar gets 2/3 of the way to the right but never goes any further. I have let it run for 20+ minutes before.

What gives?
