I've been trying to upgrade from the Enceladus 1.4 version of QGIS to 1.8 on a Thinkpad T42 running on Mint 12. When I try to upgrade from within QGIS help menu I receive the following error message: "Unable to communicate with QGIS Version server Unknown network socket error"
From the official web site, if I use the command line to install QGIS using
sudo apt-get update sudo apt-get install qgis sudo apt-get install python-qgis sudo apt-get install qgis-plugin-grass
I still get the 1.4 version.
Any thoughts? Thanks.
