You are returned to the "Install" panel, the WOLips site having been added to the list, and fully expanded to display all its offerings.
Don't selectWOLips Goodies: it cannot be installed on Ubuntu (or more generically on Linux) because of it is only for Mac or Windows.
Select features you want. If you're just getting started with WOLips you should select "WOLips" and "WOLips Goodies." Leave the other options until you are more familiar with Eclipse and WOLips and decide that you need them. (Here are some Other WOLips Install Options.) After selecting the options you want, click "Next." You'll briefly see a progress bar while Eclipse "calculates requirements and dependencies."
