I installed Eclipse on my Ubuntu machine and then the Ruby Development Tools (RDT), but it would crash when I try to alter certain features, like having line numbers, how far back to have history, and the code coloring scheme didn’t work fully. I decided to try to uninstall Eclipse by doing sudo aptitude remove Eclipse and then sudo aptitude install eclipse but instead it installed it back with the broken Ruby plugin. I also tried aptitude purge but that didn’t help either.
How can I freshly reinstall Eclipse and get a properly working Ruby plugin?
Well, I still haven’t figured out how to do it via aptitude, but downloading eclipse from their home page works.
