[QGIS-Developer] QGIS master build on Ubuntu 16.04 with python support

[Jorge Gustavo Rocha]

Hi Theuns,

Can you check which python/QT5 modules you have installed?

In my Ubuntu 16.04:

jgr at dusseldorf:~$ dpkg -l | grep pyqt5 | awk '{print $2}'
pyqt5-dev
pyqt5-dev-tools
pyqt5.qsci-dev
python-pyqt5
python-pyqt5.qtsvg
python-pyqt5.qtwebkit
python3-pyqt5
python3-pyqt5.qsci
python3-pyqt5.qtsql
python3-pyqt5.qtsvg

Regards,

Jorge
