Re: [Rdo-list] Horizon in fresh install of Havana not working

Hi! I made a clean install of Havana on a machine and by the time it finished installing, I was unable to use the dashboard as a message saying: > Something went wrong! > > An unexpected error has occurred. Try refreshing the page. If that doesn't help, contact your local administrator. I'm now trying to find what the problem is and I found the status of the dashboard in openstack-status is 500 and that neutron-dhcp-agent failed to start with this relevant part of the dhcp-agent.log: > 2013-10-25 18:00:15.550 2165 INFO neutron.common.config [-] Logging enabled! > 2013-10-25 18:00:15.551 2165 ERROR neutron.common.legacy [-] Skipping unknown group key: firewall_driver > 2013-10-25 18:00:15.585 2165 WARNING neutron.agent.linux.dhcp [-] Unable to determine dnsmasq version.

I seem to have read somewhere that a 500 status in horizon may be caused by one of the others components failing. So I'm assuming this could be my problem. Furthermore, I found that snippet may be the relevant part of the logs because I found some bug reports indicating that this could be a problem with dnsmasq. The problem is that I have version 2.66 of dnsmasq installed in the system.
