[Bug 1657930] [NEW] neutron-db-manage fails with ImportError

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

Hi,

I am upgrading our OpenStack cluster from liberty to newton. But, I am
getting the following error when I run neutron-db-manage to sync the
neutron database. The upgrade of nova was successful but the neutron
processes fail to start (I am working on controller node for now). I am
guessing it is because of the fact that first I need to sync the
database where I get the following ImportError.

I am following the official Guide of the newtown installation (to
complete the upgrade) and every thing was fine to the point before
calling neutron-db-manage.

Can you please let me know your suggestion to fix this issue?
