Eclipse Indigo marketplace

Question

I have installed Eclipse Indigo on Ubuntu 11.10, and the marketplace is not showing up under "Help" so I have added http://download.eclipse.org/releases/indigo/ to the software repositorys in "Install new software". When I try to update Eclipse with "Help" -> "Check for updates" it shows a few things that should update, but I cannot install the updates because this error:

Cannot complete the install because of a conflicting dependency.

Does anyone know what I'm doing wrong?

Answer 1

I am not sure if I had exact same error message or not. However, I was able to resolve similar issue by opening eclipse from root.

Environment:
Eclipse 3.7.0, Ubuntu 11.10

Caution: I JUST DID THIS. LOOKS LIKE WORKING FINE. HOWEVER, PLEASE LET ME KNOW IF I MESSED IT UP ANYTHING.

1. Start terminal using (ctrl + alt + t)
2. $sudo eclipse
3. in eclipse go to "help->install new software"
4. click on "available software sites". That will open "preferences" window.

5. check if you have repositories mentioned below enabled. If not, then add them.

   http://download.eclipse.org/releases/indigo
http://download.eclipse.org/eclipse/updates/3.7

6. Now go back to eclipse main window and select "help->check for updates"

7. first update eclipse platform. That will update IDE from 3.7.0 to 3.7.1
8. update all other things.
