I have managed to get Aeroo Reports working in Odoo 8.0 using the following method on a clean Ubuntu 14.04 installation:

Ubuntu 14.04 Aeroo Reports installation script:

To install Aeroo Reports and all related dependencies please do the following at a terminal in Ubuntu 14.04:

#0      cd /tmp
#1      sudo wget https://raw.githubusercontent.com/OdooCommunityWidgets/install-scripts/8.0/aeroo_reports/aeroo_install.sh
#2      sudo sh aeroo_install.sh

#3      Follow steps #31-37 in the "Ubuntu 14.04 Aeroo Reports installation method:" section below for installation instructions inside                   Odoo.

This script has a yes/no option for installing Odoo 8.0, and the Aeroo reports Odoo modules. If you have a pre-existing Odoo installation you can choose no when you get to the prompt for installing Odoo 8, and choose yes when you get to the option for installing the Aeroo Reports (aeroo_reports) modules for Odoo 8.

For installing the Aeroo Reports (aeroo_reports) modules this script assumes you already have the following directory:

/opt/odoo/custom

and

/opt/odoo/custom/addons

and it also assumes that your /etc/odoo-server.conf file includes the following directory in your addons_path line, for example:

addons_path = /opt/odoo/odoo-server/addons,/opt/odoo/custom/addons

Ubuntu 14.04 Aeroo Reports installation method:

Install Git:

#0      sudo apt-get install git

Install AerooLib:

#1      sudo apt-get install python-setuptools
#2      sudo apt-get install python-genshi python-cairo python-lxml
#3      sudo apt-get install libreoffice-script-provider-python
#4      sudo mkdir /opt/aeroo
#5      cd /opt/aeroo
#6      sudo git clone https://github.com/aeroo/aeroolib.git
#7      cd /opt/aeroo/aeroolib
#8      sudo python setup.py install

Create Init Script for OpenOffice (Headless Mode) - (see: https://www.odoo.com/forum/help-1/question/how-to-install-aeroo-reports-2780 for original post from Ahmet):

#9        sudo pico -w /etc/init.d/office
#10      Copy and paste this:

#!/bin/sh

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

#11        sudo chmod +x /etc/init.d/office
#12        sudo update-rc.d office defaults
#13        sudo /etc/init.d/office
#14        telnet localhost 8100
#15        You should see something like the following message (this means it has established a connection successfully):

Trying 127.0.0.1...

Escape character is '^]'.

Install AerooDOCS (see: https://github.com/aeroo/aeroo_docs/wiki/Installation-example-for-Ubuntu-14.04-LTS for original post):

#16      sudo apt-get install python3-pip
#17     sudo pip3 install jsonrpc2 daemonize
#18     cd /opt/aeroo
#19     sudo git clone https://github.com/aeroo/aeroo_docs.git
#20     sudo python3 /opt/aeroo/aeroo_docs/aeroo-docs start -c /etc/aeroo-docs.conf
#21     sudo ln -s /opt/aeroo/aeroo_docs/aeroo-docs /etc/init.d/aeroo-docs
#22     sudo update-rc.d aeroo-docs defaults
#23     sudo service aeroo-docs start
                 [ ! ]  If you encounter and error "Unable to lock on the pidfile while trying #16 just restart your server (sudo shutdown -r now)                         and try #16 again after reboot.

Install Odoo from Source:

#24      cd /tmp
#25     sudo wget https://raw.githubusercontent.com/lukebranch/odoo-install-scripts/master/odoo-saas4/ubuntu-14-04/odoo_install.sh
#26     sudo sh odoo_install.sh
#27     restart the server (sudo shutdown -r now)

Install Aeroo Reports:

#28    sudo apt-get install python-cups
#29    cd /opt/odoo/custom
#30    sudo git clone -b master https://github.com/aeroo/aeroo_reports.git

After following the (above) steps in this guide you should have Aeroo Reports installed correctly on your server for Ubuntu 14.04 and Odoo 8.0. You'll just need to create a database and install the required Aeroo reports modules you need for that database.

[ ! ]    Do not have aeroo_report_sample in your addons directory or you will get an error message when updating module list:
         Warning! Unmet python dependencies! No module named cups

Install report_aeroo module in Odoo database:

#31    Go to Settings >> Users >> Administrator in the backend of Odoo
#32    Tick the box next to 'Technical Features' and Save, then refresh your browser window.
#33    Go to Settings >> Update Modules List > Update
#34    Go to Settings >> Local Modules > Search for: Aeroo
#35    Install report_aeroo
#36    You'll be confronted with an installation wizard, click: Continue >> Choose Simple Authentication from the Authentication dropdown list, and add username and password: anonymous
[ ! ]     You can change the username and password in: /etc/aeroo-docs.conf if required.
#37    Click Apply and Test. You should see the following message if it was successful:

Success! Connection to the DOCS service was successfully established and PDF convertion is working.

You now have a fully operational Aeroo Reports installation in Ubuntu 14.04. If for any reason this is not working for you please post back in the comments and explain the error message you are seeing.
