Question

I using QGIS on Ubuntu and Windows, I have some questions for QGIS on Ubuntu, first I follow official details to install QGIS on Ubuntu.

On the QGIS on windows I have processing tab to show me toolbox, graphical model and more.

In that toolbox I can use algorithms from SAGA GIS,GDAL GRASS GIS and more.

My problem is on the QGIS Ubuntu I dont have that toolbox and algorithms SAGA, GRASS, GDAL, any idea why ?

Any idea how to install QGIS complete to use that algorithms on Ubuntu?

Finally in the plugins I don't have more plugins like with the Windows version, the plugins on QGIS Ubuntu is specific.

Answer 1

You have only to correctly install GRASS and SAGA. After you have installed Qgis:

• for GRASS you have to install the software in this way (link to official page):
  sudo add-apt-repository ppa:ubuntugis/ubuntugis-stable sudo apt-get update sudo apt-get install grass and then use this simple workaround (see here):
  sudo ln -s /usr/bin/grass72 /usr/bin/grass70

• for SAGA you have to compile the 2.2.3 version because that is supported at the moment, so uninstall all previous version and download it from here and then compile:
  ./configure make sudo make install
  and it will work.

  Remeber to activate GRASS7 and SAGA from Processing option settings.

Just go to the download page http://www.qgis.org/en/site/forusers/download.html and choose to download one of the two:

OSGeo4W Network Installers (32 bit or 64 bit)

.

This will install everything that you need, without you downloading and installing other stuff manually.
