Answer 1

I had the same problem in windows... and spent couple of hours to "somehow" install the new softwares.

Anyway I will explain you how I managed to install it after trying many options..

1. Start a fresh copy of eclipse
2. First tick two check boxes(Show only latest version & Contact all update sites). Make sure the check box of group items is untick.
3. Try to add software... If not showing the list of plugins/Next buttons.
4. Delete the copy of eclipse.
5. Start a fresh copy of eclipse
6. Tick only the check box for Contact all update sites.
7. Now try to add plugins. It worked for me...

Even if it sounds crap... it worked for me..

Delete your ~/.eclipse folder and restart eclipse. This is the only thing that worked for me.

Answer 4

I faced similar issue. To troubleshoot this issue follow these steps:

1. Go to windows -> show view -> error.
2. Check the error logs. In my case error was java.lang.IllegalStateException: Registry Directory not available. at org.eclipse.equinox.internal.p2.engine.SimpleProfileRegistry.restore
3. I checked my config.ini which is under eclipse -> configuration folder.
4. I found eclipse.p2.data.area has incorrect path set.
5. I set the correct path for above key and restarted eclipse. It started working. Hope it helps
