[Bug 1514731] Re: OpenStack Installation Guide for Ubuntu in Installation Guide Executable not found: conntrack (filter match = conntrack)

[Matt Kassawara]

James,

I can confirm this issue as a missing dependency. The neutron Linux
bridge and Open vSwitch L2 agents and L3 agent use a library [1] that
calls conntrack for various reasons... typically security group
management. Currently, only the neutron-l3-agent package depends on
conntrack, but neither of the L2 agents depend on it. Compute nodes
usually only run the L2 agent and therefore lack conntrack.
