How to upgrade Eclipse from 3.5 (Galileo) to 3.6 (Helios) the proper way?

Question

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.

Answer 1

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

Answer 2

Hopefully this will save somebody some trouble... I installed Helios from the zip but found that Eclipse couldn't install new plugins because of screwy dependancies. I found that I had to remove the old Eclipse folders from ~/.eclipse. Hope this helps somebody! (My system: Ubuntu 10.04, 64bit)

After installing the ppa version of 3.6 supplied by the Eclipse Team I was unable to run eclipse, got splash screen then it closed. I then downloaded the latest version of eclipse 3.6. I then extracted eclipse into the ppa installed directory. Make sure you over-write all packages. Once this was down I tried eclipse again and it was successful.
