### Ignition install fails on ubuntu

Hi,

I initially tried the binary install of ignition which leads to the following errors after following the steps on this page.

 The following packages have unmet dependencies:
ignition-edifice : Depends: libignition-gazebo5-dev but it is not going to be installed
Depends: libignition-gui5-dev but it is not going to be installed
Depends: libignition-launch4-dev but it is not going to be installed
Depends: libignition-sensors5-dev but it is not going to be installed
Depends: libignition-rendering5-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.


After failing to find a solution, I moved on to building it from source. When I try building the ignition libraries the following build errors occur:

BUILD ERRORS: These must be resolved before compiling. Missing: Qt5 Components: Core, Quick, QuickControls2, Widgets)

I have tried finding solutions online but couldn't. Installing qt5-default, libqwt-qt5-6, libqwt-qt5-dev did not resolve the issue.

Does anyone have a idea of how to fix either these installation methods?
