[Dhandapani Sattanathan]

I want to install Odoo in my existing google compute engine VM instance. Odoo server not started in GCE. So I asked help in this below SO link.

Python 3 dependencies not installed in My GCE VM instances.

these are the dependencies

sudo apt-get install python-dateutil python-feedparser python-gdata python-ldap
Reading package lists... Done
Building dependency tree      
Reading state information... Done
python-feedparser is already the newest version.
python-dateutil is already the newest version.
python-dateutil set to manually installed.
python-ldap is already the newest version.
You might want to run 'apt-get -f install' to correct these:

Hi Google, 

Could you help me, Why python 3 not installed in Google Compute engine VM instance running Debian 7?

Hi,

You can run the following commands to update and upgrade the applications currently running within the GCE instance:

$sudo apt-get update

$sudo apt-get -y upgrade

When it is upgrading the applications, you might get a message asking you to update grub, do not allow this. If this happens, choose "Keep Local settings". It will then ask you to choose a disk, so just choose the default disk. After this, it will inform you that you are not upgrading or installing Grub and basically if you would like to continue anyway, choose yes. I know of this process as I tested it myself. 

Once all applications are done upgrading, run the following command:

$python 3 -V

The output should show you something like "3.x.x" as the current python version running within the VM instance.

Thanks, Jason,

I remove all python related software in  Debian. and then tried Python 3. Now Installed successfully.

Thanks for your reply
