How to install PostgreSQL 9.2 with PostGIS 2.0 on Ubuntu 11.10 (or higher)?

Question

I have read this question: https://dba.stackexchange.com/questions/25033/install-postgis-v2-for-postgresql-v9-2, but it didn't resolve my problem.

I added the PostgreSQL backports PPA and installed the postgresql-9.2 package, but there is no package for PostGIS.

Answer 1

How to Get Started with PostGIS 2.0 on Ubuntu 12.04 (precise)

(only tested on a Oracle VM) see Migrating to Linux from Windows previous install.

sudo apt-get install python-software-properties
sudo apt-add-repository ppa:sharpie/for-science
sudo apt-add-repository ppa:sharpie/postgis-stable
sudo apt-add-repository ppa:ubuntugis/ubuntugis-unstable
sudo apt-get update
sudo apt-get install postgresql-9.2-postgis2 

Then build

You may download the source file and build it by yourself:

Install GEOS(for topology support)

wget http://download.osgeo.org/geos/geos-3.3.9.tar.bz2
tar xfj geos-3.3.9.tar.bz2
cd geos-3.3.9
./configure
make
sudo make install
cd..
