Hi everyone, I'm trying to install ODOO on my VPS,

When i run

apt-get update && apt-get install odoo

I get the following message :

Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 odoo : Depends: python3-gevent but it is not installable
        Depends: python3-passlib but it is not installable
        Depends: python3-pyldap but it is not installable
        Depends: python3-qrcode but it is not installable
        Depends: python3-suds but it is not installable
        Depends: python3-usb but it is not installable
        Depends: python3-vobject but it is not installable E: Unable to correct problems, you have held broken packages.

I have both python 2.7.9 and python 3.4.2 installed. I'm running Debian 8.8.

Please help.
