I have SAGA plugin activated in my QGIS 3.8 on a Ubuntu 18 LTS machine. However, it does not show up in my Processing Toolbox.
Could anyone help me solve this?
Check that saga is installed, in a command prompt try:
Otherwise install using:
sudo apt install saga libsaga libsaga-api-2.3.1 libsaga-dev python-saga saga-common
If it is installed, you need to check that QGIS can find the executables. The log in QGIS should show what commands have failed.
