[PKG-Openstack-devel] Bug#775133: neutron-l3-agent: conntrack package needed

[Alberto Molina Coballes]

Package: neutron-l3-agent
Version: 2014.1.3-8
Severity: normal

Dear Maintainer,

After the last upgrade, nova-l3-agent shows these log messages when a floating IP is disassociated:

The bug seems to be related to this commit [1].

If conntrack package is installed error messages no longer appear and floating IPs can be disassociated properly. Please, consider to add a dependency on conntrack to neutron-l3-agent.

Thanks
