This is close to the current qt5 branch [0] for the Debian package, it
uses Qt5/PyQt5/Python2. But because QGIS server is mostly non-functional
with Qt5 in 2.14 it's still just a testing branch.

The initial switch to Qt5 will be painful for users no matter what,
simply because the full Qt5 support is very late to arrive in QGIS.

I'm not sure if not shipping qgis in stretch is preferable over a Qt5
build which doesn't support most plugins.

Newer LTRs will be provided via backports, so eventually a fully
functional QGIS will be available to stable users.

Kind Regards,
