Some packages could not be installed. This may mean that you have  
requested an impossible situation or if you are using the unstable  
distribution that some required packages have not yet been created  
or been moved out of Incoming.  
The following information may help to resolve the situation:  

The following packages have unmet dependencies:  
  qt-components-ubuntu : Depends: libqt5core5 (>= 5.0.0) but it is not installable  
                    Depends: libqt5gui5 (>= 5.0.0) but it is not installable  
                    Depends: libqt5qml5 but it is not installable  
                    Depends: libqt5quick5 but it is not installable  
E: Unable to correct problems, you have held broken packages.  

Как указано, я установил PATH для включения /opt/qt5/bin. Мне было интересно, если эта проблема была знакома кому-либо. Большое спасибо за ваше время.
