I don't think this question is a duplicate, as the other question-askers that have reported this issue installed Eclipse using the command-line rather than the Eclipse installer.
I've been having issues with my Eclipse Neon installation and so I want to try a reinstall. I'm not sure how to do this, though, as I used the installer to install Eclipse so something like:
sudo apt-get autoremove eclipse rm -r ~/.eclipse/
Doesn't seem to work. The installer doesn't seem to have an uninstall option either, so I'm not sure what to do (I'm a Ubuntu noobie if you haven't guessed).
