For all the "not found" libraries, identify their package as you have done with apt-file search for libQt5Gui.so.5. Then install the packages with sudo apt-get install,for example:



sudo apt-get install libqt5gui5


The installation of the packages should put the libraries in the proper location so they will be found.





If files are not present, either they were installed in the wrong place (manually forced somewhere), they are the wrong architecture (i386 instead of amd64, so would be in /usr/lib/i386-linux-gnu), or the installation did not run properly (check the status of the packages with the command:



dpkg -l | grep libqt5  


The properly installed packages will have status "ii".



You could use the locate command to find the file(s) if they are somewhere else on the system, but if you installed them, that possibility is not likely.
