postgis, pgrouting, qgis install on ubuntu 14

ubuntu14-gis-install

#The following will install Postgres, pgAdmin3, PostGIS, PGRouting, QGIS, and numix (for cooler icons)

#The ubuntugis launchpad repo provides all but pgrouting, pgAdmin and of course the numix icons, it provides similar versions of software - https://launchpad.net/~ubuntugis/+archive/ubuntu/ubuntugis-unstable

#Currently on Ubuntu 14.x the universal package sources offer Posgresql 9.3, and Postgis 2.1.2 so there is no need to add repositories for these alone, unless looking for the most up-to-date version. In which case going straight to the source will be your best bet.

#! /bin/bash (include if you want to turn this into a script)

#install postgis postgresql pgadmin3 from PGDG Repo  **See alternative installation below if interested in a more up-to-date QGIS.

#Depending on which source you get GDAL from you may find conflicting packages when trying to install QGIS. The issue has been brought up in issue trackers but is yet to be resolved. If you've installed postgis from ubuntugis-unstable and want to add the latest QGIS from ubuntugis-unstable, you should have no issues.

#To install qgis 2.x
sudo apt-get update
sudo apt-get install qgis=2.0

#or opt for ubuntugis-unstable for postgis 2.1.3 and qgis 2.6
