I installed Aeroo Reports after installing OpenERP on my Ubuntu 12.04 x64 Server.

If you are a newbie and want to copy paste all of the commands you should install your OpenERP server according to my installation answer.

You can find installation answer to of OpenERP on this page : How to install OpenERP V7.0 on Ubuntu 12.04 from launchpad repository?

Or you need to change the path names

Install required packages and openoffice. (Around 500 mb installation)

sudo apt-get install openoffice.org python-genshi python-cairo python-openoffice python-lxml python-uno
sudo apt-get install zip bzr python-setuptools

Download aeroo library from launchpad and install as a python module

cd ~
bzr branch lp:aeroolib
cd aeroolib/aeroolib/
sudo python ./setup.py install

Create a new folder and download aeroo modules from launchpad to this folder with bzr.

sudo su openerp
cd /opt/openerp/v7/
bzr branch lp:aeroo
exit

Add aeroo directory to the module search path of openerp by editing the config file

sudo nano /etc/openerp-server.conf

change the addons_path as

addons_path = /opt/openerp/v7/addons,/opt/openerp/v7/web/addons,/opt/openerp/v7/aeroo

create an init script for openoffice

sudo nano /etc/init.d/office

Paste this to your script

#!/bin/sh
/usr/bin/soffice --nologo --nofirststartwizard --headless --norestore --invisible "--accept=socket,host=localhost,port=8100,tcpNoDelay=1;urp;" &

Make the file executable and add init script to the startup

sudo chmod +x /etc/init.d/office
sudo update-rc.d office defaults

Run OpenOffice

sudo /etc/init.d/office

You can test your openoffice installation by connecting to openoffice from port 8100

telnet localhost 8100

If you see an output like below it means openoffice is working ok.

Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
e--'com.sun.star.bridge.XProtocolPropertiesUrpProtocolProperties.UrpProtocolPropertiesTidE--L

Restart openerp server to be able to check the additional module directory

sudo /etc/init.d/openerp-server restart

Now you can install aeroo modules from openerp interface.

I also recorded installation from openerp interface you can watch it in Youtube. (since interface is different you may not find where to install at first) http://youtu.be/S1bKPUL6nUU
