1. First remove already added repositories which you tried to install Qgis:
Execute this in your terminal: sudo software-properties-gtk and go to Other Softwaretab.
Then remove those repositories that you added using your mentioned tutorial. Find names similar to http://qgis.org/debian and ubuntugis-unstable. Close the window.
The execute this command in terminal to update your repository: sudo apt-get update
2. Now add the QGIS repository once again to your /etc/apt/sources.list file. Do it by following these steps:
Open terminal and execute:
sudo gedit /etc/apt/sources.list
Add following lines at the last line:
deb http://qgis.org/ubuntugis trusty main
deb http://ppa.launchpad.net/ubuntugis/ubuntugis-unstable/ubuntu trusty main
Save the file and close the window.
Execute following two commands to add public key of QGIS
wget -O - http://qgis.org/downloads/qgis-2016.gpg.key | gpg --import gpg --fingerprint 073D307A618E5811
After you have verified the fingerprint you can add the key to apt with:
gpg --export --armor 073D307A618E5811 | sudo apt-key add -
Update repository by executing following command:
sudo apt-get update
3. Now install QGIS by following these steps:
First remove already installed QGIS or any residual( and broken) packages if any:
sudo apt-get autoremove sudo apt-get autoclean sudo apt-get -f install sudo apt-get autoremove qgis sudo apt-get --purge remove qgis
Install grass plugin:
sudo apt-get install grass sudo apt-get install qgis-plugin-grass
Finally install QGIS:
sudo apt-get install qgis python-qgis
when run qgis, there are some warnings; it shows no module named PyQt4.
qgis works fine now. I will update if the warning cause some problems in the future.
