On Ubuntu 18.04, using packages provided by universe repos
- QGIS 2.18.17+dfsg-1
- SAGA 2.3.1+dfsg-3build7
When starting any SAGA algorithm, QGIS crashes with a "Segmentation fault" error message.
We also tried to install QGIS 3.4 from https://qgis.org/ubuntu-ltr with both SAGA 2.3.1 (same package as above) or SAGA 7.2.0 according to https://sourceforge.net/p/saga-gis/wiki/Compiling%20SAGA%20on%20Linux/ ... In both cases, QGIS can't find SAGA.
We also tried to specify the path to SAGA lib by editing
It didn't help.
What is the setup to make QGIS work with SAGA on this OS ?
