Ok here is the thing, Im trying to install odoo v9 on a virtual server.  I created a folder inside httpdocs/ called odoo. I run this:

sudo wget -O - https://nightly.odoo.com/odoo.key | apt-key add -

I get the following error:

[root@servercorp odoo]# sudo wget -O - https://nightly.odoo.com/odoo.key | apt-key add -

Any ideas why this fails?
