At least, you still have the manual install, which leaves your current Eclipse3.5 untouched (allowing you to go back to it if 3.6 gives you too much troubles)
To get your 3.6 download running:
- Unzip the download into a directory you have complete control of, usually a directory under your username, preserving folders.
- Create a shortcut to the eclipse executable, usually in the resulting "
eclipse" folder.
- Run the program using the resulting shortcut.
- When your new eclipse install starts, point to your existing workspace.
You can continue with both 3.5 and 3.6 installed using the same workspace, or you can remove 3.5 by deselecting it from your software management program (one of several ways).
Alexander Pogrebnyak actually points out in the comment:
workspace cannot round trip 3.5->3.6->3.5.
The usual solution is to keep 3.5 and 3.6 versions of workspace in different directories.
The idea to have one workspace for each version is always the safest route to take, with each of your project imported into each respective workspace.
Note, you have to make sure your java is correctly installed (which should be already good for you, but just in case):
Installing Helios 3.6 on Ubuntu 10.10 is rather simple.
Download eclipse package from eclipse.org and extract it to a folder in your home directory.
The tricky part is setting up java6-jdk from the sun partner repository but there is a easy to follow guide:
basically you have to enable the partner repository, then install java6 jdk with:
sudo apt-get install sun-java6-jre sun-java6-plugin
and then if necessary update your java alternatives with:
# shows a list with available java alternatives:
sudo update-java-alternatives -l
# sets the alternative
sudo update-java-alternatives -s java-6-sun
sudo update-alternatives --config java
