Whenever a new plugin or a plugin update is available, QGIS will inform you âevery time QGIS startsâ, âonce a dayâ, âevery 3 daysâ, âevery weekâ, âevery 2 weeksâ or âevery monthâ. Show also experimental plugins. QGIS will show you plugins in early stages of development, which are generally unsuitable for production use. I've deleted the /Users/user/.qgis2 folder before installing 2.18; EDIT: SAGA version is 2.2.3. It is installed automatically with Qgis. EDIT 2: Exactly same symptoms in a second Mac. Reinstalled Qgis 2.14 and SAGA is live again (Saga version in Qgis 2.14 seems to be 2.1.4). EDIT 3: New attempt in a brand new Mac resulted in the same symptoms. Download the last version from here: Download Free QGIS 3.01.15 v 2018 QGIS is a Free and Open Source Geographic Information System. With this software you can create, edit, visualise, analyse and publish geospatial information on Windows, Mac, Linux, BSD (Android coming soon).
1.1 Installation
QGIS runs on Windows, various Linux distributions, Unix, Mac OS X, and Android. The QGIS project provides ready-to-use packages as well as instructions to build from the source code at https://qgis.org/en/site/forusers/download.html.
In this section, we will explain on how to install QGIS on Windows, Ubuntu and Mac OS X, as well as how to avoid the most common pitfalls.
Further installation instructions for other supported operating systems are available at http://www.qgis.org/en/site/forusers/alldownloads.html.
One of the good things of open source projects is that you have a choice between different releases. It is the same with QGIS. The following options are available, you can choose only one or you can choose all versions if you believe that you are categorized as one in 13.5 percent of population as an early adopter :D:
For this training, we will cover the steps on how to install the LR (QGIS 3) and the LTR version (QGIS 2.18).
You can have more information about the releases as well as the schedule for future releases at http://www.qgis.org/en/site/getinvolved/development/roadmap.html#release-schedule.
For an overview of the changes between releases, check out the visual change logs at http://www.qgis.org/en/site/forusers/visualchangelogs.html.
![]() 1.1.1 Installing QGIS on Windows
On Windows, there are two different options to install QGIS, the standalone installer and the OSGeo4W installer:
Qgis 2.18 Download For Windows 10
You can download the 32-bit and 64-bit OSGeo4W installers from http://osgeo4w.osgeo.org (or directly from http://download.osgeo.org/osgeo4w/osgeo4w-setup-x86.exe for the 32-bit version or http://download.osgeo.org/osgeo4w/osgeo4w-setup-x86_64.exe if you have a 64-bit version of Windows). Download the version that matches your operating system and keep it! In the future, whenever you want to change or update your system, just run it again.
We have prepared the installation files for the training. You can download the softwares from our local server in this link http://ims.geoinfo.ait.ac.th/qgis-doc/softwares/
Regardless of the installer you choose, make sure that you avoid special characters such as German umlauts or letters from alphabets other than the default Latin ones (for details, refer to https://en.wikipedia.org/wiki/ISO_basic_Latin_ alphabet) in the installation path, as they can cause problems later on, for example, during plugin installation.
When the OSGeo4W installer starts, we get to choose between Express Desktop Install, Express Web-GIS Install, and Advanced Install.
To install the QGIS LR version, we can simply select the Express Desktop Install option, and the next dialog will list the available desktop applications, such as QGIS, uDig, and GRASS GIS. We can simply select QGIS, click on Next, and confirm the necessary dependencies by clicking on Next again. Then the download and installation will start automatically. When the installation is complete, there will be desktop shortcuts and start menu entries for OSGeo4W and QGIS.
To install QGIS LTR (or DEV), we need to go through the Advanced Install option, as shown in Figure 1.1.
This installation path offers many options, such as Download Without Installing and Install from Local Directory, which can be used to download all the necessary packages on one machine and later install them on machines without Internet access. We just select Install from Internet, as shown in Figure 1.2.
Figure 1.2: Install from Internet
When selecting the installation Root Directory, as shown in the following screenshot, avoid special characters such as German umlauts or letters from alphabets other than the default Latin ones in the installation path (as mentioned before), as they can cause problems later on, for example, during plugin installation, as shown in Figure 1.3.

Then you can specify the folder (Local Package Directory) where the setup process will store the installation les as well as customize Start menu name. I recommend that you leave the default settings similar to what you can see in Figure 1.4.
Figure 1.4: Select Local Package Directory
In the Internet connection settings, it is usually not necessary to change the default settings, but if your machine is, for example, hidden behind a proxy, you will be able to specify it here (Figure 1.5.)
Then we can pick the download site. At the time of writing this book, there are three download server available, as you can see in Figure 1.6. In this tutorial, you can choose http://download.osgeo.org.
Figure 1.6: Choose a Download Site
After the installer fetches the latest package information from OSGeoâs servers, we get to pick the packages for installation. QGIS LTR is listed in the desktop category as qgis-ltr (and the DEV version is listed as qgis-dev). To select the LTR version for installation, click on the text that reads Skip, and it will change and display the version number, as shown in Figure 1.7.
As you can see in the following screenshot, the installer will automatically select all the necessary dependencies (such as GDAL, SAGA, OTB, and GRASS), so we donât have to worry about this (Figure 1.8.)
Figure 1.8: Automatic Installation of Dependent Packages
After youâve clicked on Next, the download and installation starts automatically, just as in the Express version. You have probably noticed other available QGIS packages called qgis-ltr-dev and qgis-rel-dev. These contain the latest changes (to the LTR and LR versions, respectively), which will be released as bug fix versions according to the release schedule. This makes these packages a good option if you run into an issue with a release that has been fixed recently but the bug fix version release is not out yet.
If you try to run QGIS and get a popup that says, The procedure entry point could not be located in the dynamic link library .dll, it means that you are facing a common issue on Windows systemsâa DLL conflict. This error is easy to fix; just copy the DLL file mentioned in the error message from C:/OSGeo4W/bin/ to C:/OSGeo4W/apps/qgis/bin (adjust the paths if necessary).
1.1.2 Installing QGIS on Ubuntu
On Ubuntu, the QGIS project provides packages for the LTR, LR, and DEV versions. At the time of writing this book, the Ubuntu versions Bionic, Artful, Xenial, and Trusty are supported, but you can find the latest information at http://www.qgis.org/en/site/forusers/alldownloads.html#debian-ubuntu. Be aware, however, that you can install only one version at a time.
In this section, the process to install QGIS 3 (LR) on Ubuntu 18.04 Bionic Beaver will be explained. You can refer to the previous link if you want to install QGIS LTR or DEV versions.
You can directly edit the /etc/apt/sources.list file with the following command:
Add the following line to the top or bottom of the /etc/apt/sources.list file:
Figure 1.9 shows how it looks like once the apt line of QGIS 3 is added to the /etc/apt/sources.list file.
If youâre using nano just press Ctrl + o once to save the apt line of QGIS 3 to the /etc/apt/sources.list file. You should be prompted to save the file. Just press Enter.
The GPG key should be added to your Ubuntu 18.04 Bionic Beaver machine.
Now you can verify whether the GPG key was imported correctly with the following command:

To add GPG key to apt package manager, run the following command:
The GPG key should be added to the apt package manager. https://yellowren997.weebly.com/blog/adobe-acrobat-reader-xi-download-mac.
The download and installation process of QGIS 3 should start. It should take a while.

1.1.3 Installing QGIS on Mac OS X
The general steps to install QGIS on a Mac are as follow:
There are two versions of QGIS for Mac OS X, (1) Latest Release (LR) and (2) Long Term Release (LTR). LR version depends on Python 3.6 from python.org, and LTR version depends on Python 2.7 which is included in the disk image. For both versions, Read Me file is included.
1.1.3.1 QGIS LR installation on Mac OS X
The steps to install QGIS LR (QGIS 3) on Mac OS X are as follows:
