[Brent Eagles (beagles)]

https://review.openstack.org/#/c/401041/ may have fixed this. It was merged some time ago however so we may need to poke the packagers on this.

[Brent Eagles (beagles)]

Seems to be a package version. 3.2.1 on newton and 3.1.1 for master/ocata so the package isn't getting updated with fixes made in 3.1.1

[Brent Eagles (beagles)]

FWIW, considering that this particular case is specific to an ODL package version number, I'm not sure that this should impact TripleO RC1 as it's really on the networking-ODL packagers to straighten out.

[Isaku Yamahata (yamahata)]

networking-odl 3.x.x is newton release. Not ocata.
Please use source tree corresponging to ocata release.

The request to cut stable/ocata branch is at https://review.openstack.org/#/c/434465/
Once it is merged, networking-odl has stable/ocata branch. Please use that branch. (or master branch until cutting it.)

[Isaku Yamahata (yamahata)]

btw networking-odl ocata will have the version of 4.x.x

[Brent Eagles (beagles)]

Ocata/master patch has been updated with version 4.0.1. This should get us a little farther along. Marius can you retest?
