Where was that error message printed? That just looks like the launchpad text.
Please describe the steps you performed (you say you installed Opera - how? and uninstalled it - how?), the error messages you saw and how they appeared (did a window appear with the error in it?). What happens in software-centre - does the software centre appear? Does it all work until you ask it to install something?
