Could not mark all packages for installation or upgrade

I have got the Update Package in Linux Mint, however, this seems to be broken as I received an error on starting the update. I tried removing the package but it also won't let me. I am certain that there are contents in this update that is stopping me from running the update but I am not sure what to do next. I am asking for help on resolving this matter. Thank you.

Make sure that all required responsibilities are added and enabled in the preferences.
Pglgui:
Depends: libpolkit-qt-1-1 but it is installable
Depends: libqtcore4 (>=4:4.7.0 ~ beta1) but 4:4.6.2-0ubuntu4.3 is to be installed
