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, so any advice how to get the latest QGIS version including a working Python plugin would be highly appreciated.

Best regards, T.
