Will have a look, thanks.

edit : nope, been there. It's talking about an xterm and I only know of the terminal. Same thing? if so, I've tried each command there and it didn't work. Either that or the bitcoin folder is somewhere and I don't know how to get to it.

edit 2 : it says "Just launch the package manager and install bitcoin-qt" I don't even know what the package manager is, will have to search around again but I think I'm still stuck.
