I want to install QGIS 3.4 above and did exactly the same as this page: QGIS Installers

and tried the codes below having no error at all:

(1) add the following lines to /etc/apt/sources.list

deb https://qgis.org/ubuntu xenial main

deb-src https://qgis.org/ubuntu xenial main

(2) wget -O - https://qgis.org/downloads/qgis-2017.gpg.key | gpg --import

gpg --fingerprint CAEB3DC3BDF7FB45 which gives the results below:

pub 2048R/BDF7FB45 2017-08-16 [expires: 2019-08-16] Key fingerprint = 61E0 A086 749E 463E DE50 2255 CAEB 3DC3 BDF7 FB45 uid QGIS Archive Automatic Signing Key (2017) sub 2048R/E959BBCF 2017-08-16 [expires: 2019-08-16]


gpg --export --armor CAEB3DC3BDF7FB45 | sudo apt-key add -

at last:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-key CAEB3DC3BDF7FB45

(3) sudo apt-get update

(4) sudo apt-get install qgis python-qgis qgis-plugin-grass

every thing goes fine except that these codes installs only QGIS 2.18 but not 3.4 above?

I have tried other repositories as well and it still goes the same and installs QGIS 2.18

I need a solution and I need this software on my Ubuntu.



If you follow the instructions from the QGIS Installers page, you will see the following information under the "Supported distribution versions:" table:

Ubuntu 16.04 (LTS) xenial [5]

[5] 3.0 and above only available with ubuntugis-unstable (plain xenial lacks GDAL2)

enter image description here

So, add the ubuntugis-unstable ppa:

sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable

Then use the "Release with ubuntugis-unstable dependencies" repository (https://qgis.org/ubuntugis) in your /etc/apt/sources.list

deb https://qgis.org/ubuntugis xenial main
deb-src https://qgis.org/ubuntugis xenial main

You should then be able to install QGIS 3.4.2 according to the packages list:

Description: Geographic Information System (GIS)
 A Geographic Information System (GIS) manages, analyzes, and displays
 databases of geographic information. QGIS supports shape file viewing and
 editing, spatial data storage with PostgreSQL/PostGIS, projection on-the-fly,
 map composition, and a number of other features via a plugin interface. QGIS
 also supports display of various georeferenced raster and Digital Elevation
 Model (DEM) formats including GeoTIFF, Arc/Info ASCII Grid, and USGS ASCII
  • It might be necessary to add the ubuntugis key as well. Before installing, use sudo apt-cache policy qgis to see what is available for you. – AndreJ Dec 9 '18 at 4:57
  • @AndreJ possible, but unlikely as add-apt-repository by default adds the key. – user2856 Dec 9 '18 at 5:45
  • @Luke It worked perfectly. thank you for your great details. Regards – Nima Dolatabadi Dec 10 '18 at 13:08
