How to upgrade OpenERP on Ubuntu Linux

Here are my steps to upgrade OpenERP from 5.0.2 release to 5.0.3 on Ubuntu Linux. Please note this procedure only applies when OpenERP 5.0.2 was previously installed from source code (.tar.gz files). This upgrade is easy because both releases share the same Python libraries. This procedure is expected to work with the next OpenERP releases.

TIP: Copy and paste the following lines on a linux terminal

cd /opt
sudo apt-get install wget -y
sudo wget http://www.openerp.com/download/stable/source/openerp-server-5.0.3.tar.gz
sudo wget http://www.openerp.com/download/stable/source/openerp-client-5.0.3.tar.gz
sudo wget http://www.openerp.com/download/stable/source/openerp-web-5.0.3.tar.gz
sudo tar xvzf openerp-server-5.0.3.tar.gz
sudo tar xvzf openerp-client-5.0.3.tar.gz
sudo tar xvzf openerp-web-5.0.3.tar.gz
cd /opt/openerp-server-5.0.3
sudo python setup.py install
cd /opt/openerp-client-5.0.3
sudo python setup.py install
cd /opt/openerp-web-5.0.3
sudo python setup.py install
