For the purpose of installing Master PDF Editor, which I would use to troubleshoot a separate problem, I need a more up-to-date version of QT. When I run sudo dpkg -i master-pdf-editor-4.2.70_qt5.amd64.deb I get the following error:
dpkg: dependency problems prevent configuration of master-pdf-editor:
master-pdf-editor depends on libqt5svg5 (>= 5.4); however:
Version of libqt5svg5:amd64 on system is 5.2.1-1.
master-pdf-editor depends on libqt5network5 (>= 5.4); however:

I have tried following these instruction (for QT 5.9) but at the following step:
Edit a file named “defaults.list” in the same directory. Add the following line.
text/qtcreator=Qt-Creator.desktop;
I have the problem that no file defaults.list exists in /.local/share/applications. Proceeding without completing this step doesn't seem to update the various libqt5 packages that need updating. What should I do to meet the Master PDF Editor dependencies?
~/.local/share/applications. That said, I still don't see a step that could've placed the file in there, so might need to create it. Why the hassle though, 14.04 is ancient, perhaps it's better to just upgrade the system? – Hi-Angel Aug 01 '17 at 22:57/.local/share/applications. I would be happy to upgrade my system but I worry that it may break something. Namely, I don't want my OpenAI Gym to break, nor my DropBox folder. Is upgrading generally safe? I know 16.04 includes the versions of QT I need so presumably upgrading to 16.04 is a solution. – Blackmill Aug 01 '17 at 23:03
