this is full error message

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?

Dave

Hi
  OK, so it looks like you have a few errors:

Error in file "/usr/share/applications/kde4/kplayer.desktop": "uri/rtspu" is an invalid MIME type ("uri" is an unregistered media type)
Traceback (most recent call last):
  File "/usr/bin/update-software-center", line 34, in <module>
    from softwarecenter.db.update import rebuild database
  File "/usr/share/software-center/softwarecenter/db/update.py", line 70, in <module>
    cataloged_times = cPickle.load(open(CF))
dpkg: error processing opera (--remove):
  subprocess installed post-removal script returned error exit status 1

Opera isn't supported on ubuntu launchpad bug tracker as I understand it, however the errors about kplayer and software-centre may be unrelated

I'd try uninstalling kplayer and see if that helps. I would do this from a terminal window with the command:

sudo dpkg --purge kplayer kplayer-data kplayer-doc

and then see if software-center is any happier with the other problems.

Dave

i removed kplayer then i was try to remove opera but the same message appear
see the link
