Update on testing results from my end, based on https://bugs.launchpad.net/ubuntu/+source/neutron/+bug/1927868/comments/19.
Attempts to upgrade from train to any of the ussuri package versions in the ussuri-staging PPA [1] hit the bug or a similar bad state of routers (both routers are DOWN, or both are UP with no IP address, or one is DOWN and one is UP with no IP address). [1] https://launchpad.net/~ubuntu-cloud-archive/+archive/ubuntu/ussuri- staging/+packages?field.name_filter=neutron&field.status_filter=&field.series_filter= So I think this might be an issue between 15.3.4 and commit 3e8abb9a8f (the latter being the upstream commit that the earliest package snapshot in ussuri-staging is based on). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1927868 Title: vRouter not working after update to 16.3.1 To manage notifications about this bug go to: https://bugs.launchpad.net/neutron/+bug/1927868/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
