I have a problem installing the new adt (version

after going to help / software updates / find and install / search for new features to install / new remote site
enter the site: https://dl-ssl.google.com/android/eclipse/
select adt and android editors...
I get the following message:
You cannot install in the site "file:/etc/eclipse/". It is considered non updateable. The site is marked as read only.
Any ideas?
btw, I am using eclipse under linux
Thanks
