Hi, sorry to say that, but it will not heal itself. You both seem to have leftovers from kdenext repo, which is no longer available. The packages are on your system now and not upgradable because of dependency issues ( /me no apt guru, perhaps someone else can can explain better).
So manual work is needed. You should delete the packages mentioned in the error messages and take note (!) of what apt does and which other packages are removed with the commands you issue (pipe output to a text file or such). Then reinstall those packages, I don't know if it is necessary to force the version in some cases. You should as well search your system for other suspect packages, meaning those with 'siduction' or 'really' in the package version string.
All this is not for granted, so have a backup. If unsure, come to IRC where might be better experts than me, prepare to work and chat in text mode and know how to use a paste service
