Unable to run in Debian GNU/Linux release 9 _Stretch_.

I tried to run this software you have created because I am to query PostGIS, but I wasn't being able to get qgis working smoothly and not becoming unresponsive. But I think I figured it out at last, so I won't be pursuing your solution any longer while I can. Anyway this was happening when running on Debian:

$ uname -a
