I've never had trouble with this. On my systems I've never needed sudo privileges to access /etc/neutron. Is it possible this is just a misconfiguration somehow? Did you touch /etc/neutron as a privileged user at some point and change the permissions?

[Dongcan Ye (hellochosen)]

@Ryan, I reinstall devstack in an new OS.
First time, meet the following error info:
http://paste.openstack.org/show/524203/

Then I run ./unstack.sh and ./stack.sh, the error info appears:
http://paste.openstack.org/show/524209/

I did't know the relationship between this two errors.

@Dongcan Ye

You can refer to the document https://review.openstack.org/#/c/335871/ to enable the neutron-dynamic-routing.

Reason: Thanks for all review.

Hmm, if I read the instructions in https://review.openstack.org/#/c/335871/ correctly, this will try to install neutron-dynamic-routing on top of nova-network, i.e. without neutron being enabled. Maybe that is bound to be broken anyway?

[Ryan Tidwell (ryan-tidwell)]

Yeah, reading the docs with fresh eyes it does sort of skip over the step of enabling neutron and disabling nova-network. BGP won't work unless neutron is running, so I suppose it's understood that neutron is a pre-requisite. That in turn would mean that nova-network should be disabled. It certainly wouldn't hurt to show a more complete example of the local.conf snippets you might use that illustrates enabling neutron and disabling nova-network.

    Fix bug for Permission denied

    Permission denied for creating directory '/etc/neutron', here we
    use root privilege for creating the directory, then set the owner
    as STACK_USER.
