Today QGIS 2.0 was officially released and we will come up with several tutorials in the next weeks. First of all: the installation.
As we are fans of open source we would like to show you the installation on a fresh build Ubuntu system:
Installation on Ubuntu
QGIS strongly depends on the grass libraries so as a first step we will install them:
sudo apt-get install grass
As QGIS 2.0 is not part of the official Ubuntu repositories (aka software provider) we need to enhance the list of software providers. Open up the terminal and edit the sources.list which helds this list:
sudo gedit /etc/apt/sources.list
Now the standard editor of Ubuntu open up and you should add the following lines at the end of the file:
deb http://qgis.org/debian precise main deb-src http://qgis.org/debian precise main
If you are running Ubuntu in a different/older version change precise according to your needs. The official support has only precise pangolin aka 12.04 as the latest release. Save and close the file.
The download page of QGIS states that you should add the keys via the terminal. The key has changed and is not longer the one mentioned at qgis.org:
Open up terminal and type
gpg --keyserver keyserver.ubuntu.com --recv 47765B75 gpg --export --armor 47765B75 | sudo apt-key add -
Next of it we need to install one more software provider:
sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable
To update your local catalog of available software use the heavy line
sudo apt-get update
And in the end we are ready to go to install QGIS 2.0 Dufour
sudo apt-get install qgis python-qgis qgis-plugin-grass
This now takes a while but it will install QGIS on your Ubuntu system. In the end try to start QGIS. If it fails it is possible that you need to make yourself the owner of the qgis folder:
sudo chown -R "your username" ~/.qgis2
And here the video for it:
Have fun and enjoy your QGIS!
