Problem on installing Vertica on Ubuntu Server 14.04

Hi all,


I’m having difficulties to install Vertica on top of Ubuntu server 14.04 in a Canonical Openstack environment.

I performed the necessary preparation steps. When I run install_vertica script, I get the following output:



root@vertica-ubuntu:/home/ubuntu# /opt/vertica/sbin/install_vertica --hosts --deb /home/ubuntu/vertica_setup/vertica_8.0.1-0_amd64.deb

    raw_macs = raw_macs.split()

AttributeError: 'NoneType' object has no attribute 'split'

Installation FAILED with errors.


Installation stopped before any changes were made.


Then I search on the net about this error and one recommendation was to use “--ignore-install-config” switch and I tried it:


root@vertica-ubuntu:/home/ubuntu# /opt/vertica/sbin/install_vertica --hosts --deb /home/ubuntu/vertica_setup/vertica_8.0.1-0_amd64.deb --ignore-install-config

AdminTools and your existing Vertica databases may be unavailable.

Investigate the above warnings/errors and re-run installation.




So as you can see from the output, installation is failing to start because of the same error, shown in yellow.

Can you help me on this matter?

         Please set your IO Scheduler as below 


    echo deadline > /sys/block/sda/queue/scheduler



    Once you set the io scheduler, try to install vertica
