Actually, at the moment for ubuntu I only have Geany istalled - it is pretty much enough for me. My previous computer started to have occasional problems, so I moved to using a secondary computer. And as I don't enjoy spending time with setting up the system, I've been running on rather minimal configuration for several months =)

Do you need the latest version of CodeBlocks for some spesific reason? If you want easy installation, just go with the version available on Ubuntu Software center?
