I am trying to install QGIS3 on my Ubuntu 16.04 Xenial.

Following the instructions on the QGIS Website I added the following lines to my sources.list:

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

I run

sudo apt-get update

and try to execute the installation:

sudo apt-get install qgis python-qgis qgis-plugin-grass

For each of the packages I get the answer that there are several missing packages:

python-qgis : Depends: python-qgis-common (= 1:3.0.0+24xenial-ubuntugis) but it is not going to be installed
           Depends: libqgispython3.0.0 but it is not going to be installed
           Depends: libqgis-analysis3.0.0 but it is not going to be installed
           Depends: libqgis-core3.0.0 but it is not going to be installed
           Depends: libqgis-gui3.0.0 but it is not going to be installed
           Depends: libqgis-server3.0.0 but it is not going to be installed
 qgis : Depends: gdal-abi-2-2-2 but it is not installable
    Depends: libgdal20 (>= 1.8.0) but it is not installable
    Depends: libqgis-analysis3.0.0 but it is not going to be installed
    Depends: libqgis-app3.0.0 but it is not going to be installed
    Depends: libqgis-core3.0.0 but it is not going to be installed
    Depends: libqgis-gui3.0.0 but it is not going to be installed
    Depends: qgis-providers (= 1:3.0.0+24xenial-ubuntugis) but it is not going to be installed
 qgis-plugin-grass : Depends: qgis-provider-grass (= 1:3.0.0+24xenial-ubuntugis) but it is not going to be installed
                 Depends: libgdal20 (>= 1.8.0) but it is not installable
                 Depends: libqgis-app3.0.0 but it is not going to be installed
                 Depends: libqgis-core3.0.0 but it is not going to be installed
                 Depends: libqgis-gui3.0.0 but it is not going to be installed
                 Depends: libqgisgrass7-3.0.0 but it is not going to be installed
                 Depends: grass740 but it is not installable

Most interesting is that some packages are not installable: gdal-abi-2-2-2, libgdal20, grass740

Any idea how to solve this?

  • If you don't have LTS xenial version I think that QGIS 3 is not installable because your Ubuntu is too old. Read this note: https://www.qgis.org/en/site/forusers/alldownloads.html#id9 – xunilk Mar 21 '18 at 02:41

Tested 29/06/2018 

--QGIS 3 Ubuntu 16.04

sudo sh -c 'echo "deb https://qgis.org/ubuntugis  xenial main" >> /etc/apt/sources.list'
sudo sh -c 'echo "deb-src https://qgis.org/ubuntugis xenial main" >> /etc/apt/sources.list'
sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable

wget -O - https://qgis.org/downloads/qgis-2017.gpg.key | gpg --import
gpg --fingerprint CAEB3DC3BDF7FB45
gpg --export --armor CAEB3DC3BDF7FB45 | sudo apt-key add -

sudo apt-get update && sudo apt-get install qgis python-qgis qgis-plugin-grass

For QGIS3 on xenial you have to use ubuntugis-unstable ppa

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

  • Indeed that worked for me today, they should probably update QGIS Installer docs – adamczi May 08 '18 at 14:29
  • @adamczi I think https://www.qgis.org/en/site/forusers/alldownloads.html#id10 is clear enough. – AndreJ May 25 '18 at 14:09

    you're right @AndreJ, I must have read it incorrectly or maybe it changed. I'd also like to point out that universe was needed to be enabled on my Ubuntus to make it work (otherwise I got a lot of 'not going to be installed' stuff) – adamczi May 25 '18 at 14:24
  • I guess you would not be able to install any software if you kicked off the main ubuntu repository. Unless you try to self-compile everything... – AndreJ May 25 '18 at 15:54

If you have conda, you can do:

conda config --add channels conda-forge
conda create -n qgis3 -c ceholden -c QuantStack qgis=3
source activate qgis3
qgis

#/etc/source.list.d/ubuntugis.list deb https://qgis.org/ubuntugis xenial main deb-src https://qgis.org/ubuntugis xenial main

and

sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable sudo apt update sudo apt install qgis

is what my colleague seems to have found out.

Before that, I managed to install it by manually downloading all dependency *.deb files from https://qgis.org/ubuntugis/pool/main/q/qgis/ and installing them with gdebi.

I was able to install QGis 3.4 on Ubuntu 16.04 by removing the libsqlite3.so.0 symbolic link 

sudo rm /usr/local/lib/libsqlite3.so.0

I have Linux Mint 18.3 (Ubuntu 16.04 ) computer, I followed the following aforementioned guidelines:

--QGIS 3 Ubuntu 16.04

sudo sh -c 'echo "deb https://qgis.org/ubuntugis  xenial main" >> /etc/apt/sources.list'
sudo sh -c 'echo "deb-src https://qgis.org/ubuntugis xenial main" >> /etc/apt/sources.list'
sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable

wget -O - https://qgis.org/downloads/qgis-2017.gpg.key | gpg --import
gpg --fingerprint CAEB3DC3BDF7FB45
gpg --export --armor CAEB3DC3BDF7FB45 | sudo apt-key add -

sudo apt-get update
sudo apt-get update && sudo apt-get install qgis python-qgis qgis-plugin-grass

However I was still getting unmanaged dependency errors. Hence I tried with aptitude as follows:

sudo aptitude install qgis python-qgis

To resolve the dependency I selected :

 Install the following packages:                         
1)    python3-psycopg2 [2.7.6.1-3.pgdg16.04+1 (xenial-pgdg)]

and accepted the proposed solution. After the package manager installed all of the qgis libraries, I could observe qgis 3.4.4 Maedira on my screen with joy.
