I've installed Eclipse Mars, and need to install the SVN plugin. When I click
menu: Help > Install new software, I select All Available Sites, and normally something happens in the main window, items appearing or activity indicating that it's downloading information.
Now I don't see anything happening. I can click the "select all" button, and then 2116 items are selected. Nothing appears in the window. At first I thought this was a problem with the Dark Theme I used, but changing that to the Classic theme didn't help. Restarting didn't help.
What can I do to install plugins in Eclipse Mars on Ubuntu 14.04?
