I've just tried to install the latest version of QGIS on Linux Mint 15 Mate using 'sudo apt-get update' and 'sudo apt-get install qgis'. However, QGIS gives me the error message 'Couldn't load PyQGIS. Python support will be disabled.'. Also, the installed QGIS version turns out to be 1.7.5 while I would prefer 1.8.0 or even 2.0.
I am pretty new to the world of Linux in general.
I think the best option if you want to work with several GIS applications and a Ubuntu-based system is the UbuntuGIS repository. Adding it to your sources is very easy, just enter this commands in the terminal, one at a time.
sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable
sudo apt-get update
sudo apt-get install qgis
After that you will have QGIS 2.0 installed in your system. There are some plugins available like the grass one wich is very useful for GRASS integration. In my case, I had an error running QGIS without root privileges, which I solved giving permissions to the QGIS folder:
(In the /home/user folder)
sudo chmod -R +rwx .qgis2
After that it should run fine just from the application menu.
