I notice this question has been asked a few times but I don't really like the solution with two Eclipses in parallel. I just want my Galileo upgraded to Helios with preservation of all settings, plugins and workspaces, without the mumbo-jumbo like copying plugins manually and stuff. I've got the Android plugin, the C/C++ plugin, the PyDev plugin and what not more.
Is there a quick and sure way to upgrade Eclipse like this? I've found some instructions on the Eclipse wiki, but it doesn't seem to work with my system (Ubuntu 10.04; I add the Helios site and then Check for Updates, but it doesn't take Helios as an update for Eclipse). Has someone found a solution for this?
UPDATE: The way described in the wiki seems to work on my Windows-installed Eclipse, Check For Updates lists "Eclipse SDK v.3.6.0" as an available update.
You cannot. You have to download, uncompress and run it without the ubuntu repository. In this scenario you can upgrade without problems ;-)
If you want to use Helios through the ubuntu repository you have to wait beyond Maverick (10.10) as you can see here: https://launchpad.net/ubuntu/+source/eclipse
